Description

A kind of chamber mirror applicator auxiliary hook

Technical field:

This utility model belongs to technical field of medical instruments, relates to a kind of matching used auxiliary hook of chamber mirror applicator for minimally invasive surgery, particularly a kind of chamber mirror applicator auxiliary hook.

Background technology:

Minimally invasive surgery is by microtrauma or Mini approach, by special instrument, physical energy or chemical agent are sent into inside of human body, complete pathological changes in human body, deformity, the deactivation of wound, excision, the surgical procedures such as reparation or reconstruction, to reach the medical science branch of therapeutic purposes, are characterized in that otch is little, wound is little, recover fast, painful few, patient's wound is significantly less than corresponding traditional surgery, in recent years along with the development of minimally invasive surgery, and peritoneoscope, the endoscope-assistant surgery Yi departments of general surgery such as thoracoscope, Urology Surgery, a plurality of professional extensive uses such as gynecological and thoracic surgery, and in these operation techniques, applicator (comprising titanium clamp pincers and Hme-0-lok) is the most frequently used and important tool, for example Chinese patent 96230252 discloses a kind of titanium clamp pincers, Chinese patent 200810039978 discloses a kind of burst titanium clip, Chinese patent 201220058375 discloses a kind of automatic-repeating formula titanium clamp pincers structure of improvement etc., for folder, closes blood vessel, lymphatic vessel, ureter etc., and Bleeding control, lymphatic fistula, leakage of urine etc., but press from both sides in closed procedure often because gap is too small in operation, angle is not good enough, the reasons such as the visual field is unclear, cause clamp difficulty or carry its hetero-organization secretly, and the separation of not only having wasted time and energy is carried secretly and organized but also carry out risk to surgical band, and designs a kind of auxiliary hook that coordinates applicator to use, and is applied in operation because applicator cannot accurately be carried secretly, separation difficulty, angle is controlled the operation of difficulty etc., and not only accuracy height but also use conveniently, had not yet to see open use and the bibliographical information of applicator auxiliary hook, and more this Application of device is not in clinical information.

Summary of the invention:

Goal of the invention of the present utility model is to overcome the shortcoming that prior art exists, seek to design a kind of chamber mirror applicator auxiliary hook for minimally invasive surgery, to control the folder that difficulty is high in the operating process of solution operator, close and carry secretly risk, reduce operation easier and operation risk.

To achieve these goals, agent structure of the present utility model comprises tissue hook, front sleeve, bridging piece, rear sleeve, operation ring, pull bar, gib head and bending, the front end edge of the front sleeve of tubular structure is fixedly connected with and is shaped with tissue hook, the front end bending-type of the tissue hook of rigidity metallic rod shaped structure is shaped with gib head, be used for hooking up muscular tissue, the tissue hook folding type of the rear end of gib head forms bending, is convenient to flexible operating; With on the rear sleeve rear end side of front sleeve symmetrical structure, be fixedly shaped with rigidity metallic pull bar, on the other end of pull bar, be fixedly shaped with the operation ring that can be inserted on finger, between front sleeve and rear sleeve, be fixedly shaped with the bridging piece of the arc-shaped structure that connects two sleeves, the structure that front sleeve, rear sleeve and bridging piece form or the metal tube cutting consisting of front sleeve and rear sleeve form, the part that its bridging piece is metal tube; The length of bridging piece is 5-20cm, and the internal diameter of anterior cannula and rear sleeve is greater than the external diameter of matching used chamber mirror applicator, so that it is nimble to slide.

Compared with prior art, it is reasonable in design for this utility model, and principle is reliable, and structure and making step are simple, and auxiliary hook can freely be torn open also with applicator, easy for operation, safe and reliable.

Accompanying drawing explanation:

Fig. 1 is agent structure principle schematic of the present utility model.

Fig. 2 is that this utility model and chamber mirror applicator are used in conjunction with structural principle schematic diagram.

The specific embodiment:

Below in conjunction with accompanying drawing and by embodiment, this utility model is described in further detail.

Embodiment:

The agent structure of the present embodiment comprises tissue hook 1, front sleeve 2, bridging piece 3, rear sleeve 4, operation ring 5, pull bar 6, gib head 7 and bending 8, the front end edge of the front sleeve 2 of tubular structure is fixedly connected with and is shaped with tissue hook 1, the front end bending-type of the tissue hook 1 of rigidity metallic rod shaped structure is shaped with gib head 7, be used for hooking up muscular tissue, tissue hook 1 folding type of the rear end of gib head 7 forms bending 8, is convenient to flexible operating; With on the rear sleeve 4 rear end sides of front sleeve 2 symmetrical structures, be fixedly shaped with rigidity metallic pull bar 6, on the other end of pull bar 6, be fixedly shaped with the operation ring 5 that can be inserted on finger, between front sleeve 2 and rear sleeve 4, be fixedly shaped with the bridging piece 3 of the arc-shaped structure that connects two sleeves, the structure that front sleeve 2, rear sleeve 4 and bridging piece 3 form or the metal tube cutting consisting of front sleeve 2 and rear sleeve 4 form, the part that its bridging piece 3 is metal tube; The length of bridging piece 3 is 5-20cm, and the internal diameter of anterior cannula 2 and rear sleeve 4 is greater than the external diameter of matching used chamber mirror applicator, so that it is nimble to slide.

The present embodiment is applied to endoscope-assistant surgery and need to coordinates applicator to hook up the occasion that applicator is difficult for gripping muscle, during use, applicator is inserted between the sleeve of front and back, allow the tong chops place of gib head 7 in applicator, by operation, encircle the activity of 5 control tissue hook 1, coordinate applicator to realize hooking up of muscular tissue or gripping, its flexible operation, safe and reliable.
