Abstract

The invention provides medical forceps which comprise a handle, cranks, a shaft, a forceps head and two fixing plates. One end of each crank is fixedly connected with the handle while the other end of the crank is fixedly connected with the forceps head; the shaft is arranged at a joint of the two cranks; and the two fixing plates are fixedly connected onto the forceps head, one surface of each fixing plate is a concave curved surface, and the concave curved surfaces of the two fixing plates are arranged oppositely. The medical forceps have the advantages that a tubular object is clamped conveniently; the object can be clamped firmly; the object can be clamped firmly for a long time, and object clamping tightness degree is easy to adjust; and surgery steps are optimized, operation time is shortened, and beneficial conditions are created for postoperative rehabilitation of a child patient.

Description

Medical calm

Technical field

The present invention relates to a kind of medical instruments field, be particularly useful for the operating medical calm of infant.

Background technology

At present; In the infant surgical operation; Especially in the operation of infant complicated congenital heart disease, usually will carry out upper and lower cavity metal right angle intubate, this metal right angle intubate is made up of metal tube and plastic conduit two parts; Front end is L shaped metal tube, and the metal tube rear end connects soft plastic conduit.After doing little otch on last (descending) caval vein, the doctor will insert metal right angle intubate in the caval vein, and; When putting this type of intubate; Angle, dynamics to inserting all have very high requirement, and in most cases the doctor can singlehanded hold in the correct position that metal tube places it in the thoracic cavity, but the infant thoracic cavity is little; Doctor's one hand is held metal tube and can't be goed deep in the infant thoracic cavity; Can't carry out stable location to its front end metal tube and hold soft plastic conduit,, cause situation such as operating time prolongation, patient's bleeding increase so difficult intubation appears in regular meeting clinically.So, how to research and develop the auxiliary doctor of a kind of suitable medical apparatus and instruments and when operation, can carry out stable position metal right angle intubate, become the technical barrier of being badly in need of solution clinically.

Summary of the invention

Main purpose of the present invention is to provide a kind of medical calm, solves in the prior art when the infant surgical operation, is difficult to metal right angle intubate is carried out the localized problem of accurate intubate.

For reaching above-mentioned purpose, the invention provides a kind of medical calm, comprise handle, crank, axle and binding clip, also comprise stator, the affixed handle of said crank one end, the affixed binding clip of the other end; Said axle is arranged on the junction of two cranks; Said stator has two, is fixed on the binding clip, and stator one surface is a concave curved surface, and the concave curved surface of two stators is for being oppositely arranged.It is that fixedly the effect of tube is better because tube is clamped in this setting more easily that stator is made as concave curved surface.

Further, said concave curved surface is a matsurface.Concave curved surface being made as uneven, is because can increase frictional force during the clamping object, more is prone to clip object.

Further, said stator material is elastic materials such as rubber.

Further, said medical calm also comprises two card articles, and said two card articles are fixed in respectively on two cranks; Fixing position is between its corresponding handle and axle; And card article is equipped with a plurality of latches for being oppositely arranged on each card article, and the latch on two card articles is engaged.Be provided with latch and be in order to fix object for a long time, need not operator and continue firmly more to help the doctor and in operation, operate, being provided with a plurality of latches is for the ease of regulating the clamping degree to object.

Further, the latch spacing on the said card article equates.

The invention has the advantages that:

(1) is convenient to clamp tube;

(2) clip the effective of object;

(3) can clip object for a long time, and be easy to regulate the tightness of clamping object;

(4) optimizing surgical operation step, shortening operating time, is that advantageous conditions is created in the rehabilitation of infant postoperative.

The specific embodiment

This specific embodiment will combine accompanying drawing to do further explanation.

As depicted in figs. 1 and 2, a kind of medical calm comprises handle, crank, axle 3, binding clip, card article and stator.Said handle comprises first handle 101 and second handle 102; Said crank comprises first crank 201 and second crank 202; The infall of first crank 201 and second crank 202 is provided with one 3; Said binding clip comprises first binding clip 401 and second binding clip 402; First crank, 201 two ends are connected with first handle 101 respectively and first binding clip, 401, the second cranks, 202 two ends are connected with the second handle 102 and second binding clip 402 respectively.

Said card article comprises first card article 601 and second card article 602; Vertically be fixed in contiguous handle place on first crank 201 and second crank 202 respectively; Two card articles are for being oppositely arranged, and first card article 601 and second card article 602 be respectively equipped with can be engaged first latch 701 and second latch 702.

Said stator one surface is a concave curved surface, and this surface irregularity, and stator comprises first stator 501 and second stator 502, be separately fixed on first binding clip 401 and second binding clip 402, and the concave surface of two stators is oppositely arranged;

Stator material on the medical calm of the present invention is a rubber, miscellaneous part material selection high-quality Ti-Ni alloy.

When infant is undergone surgery, clamp earlier the junction of metal tube and plastic conduit on the metal right angle intubate, thereby metal right angle intubate is firmly vised with two stators; Next the doctor can deliver to metal right angle intubate on the intrathoracic correct position of infant through holding first handle 101 and second handle 102, carries out the intubate operation.Find that in operating process in the art angle or position are improper, can release handle, clamp the diverse location on the metal right angle intubate again, it is adjusted to suitable position and angle.

If think to fix object for a long time; Need not operator continues firmly; Can on medical calm, further be provided with card article, when infant is undergone surgery, clamp earlier the junction of metal tube and plastic conduit on the metal right angle intubate with two stators; Then through with the latch interlock mutually on first card article 601 and second card article 602, thereby metal right angle intubate is firmly vised; Next the doctor can deliver to metal right angle intubate on the intrathoracic correct position of infant through holding first handle 101 and second handle 102, carries out the intubate operation; First latch 701 and second latch 702 that unclamp interlock at last get final product.Find that in operating process in the art angle or position are improper, can unclamp the latch of interlock, clamp the diverse location on the metal right angle intubate again, it is adjusted to suitable position and angle.

Latch spacing on the said card article equates.

The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
