Abstract

The utility model belongs to the field of medical instrument auxiliary tools, and particularly relates to a puncture fixing device for fixing a laparoscope puncture device. The puncture fixing device comprises a guide piece, a self-folding hook piece and a hoop assembly; when the self-folding hook piece and the guide piece relatively slide to be at certain positions, the folding section of the self-folding hook piece can be bent to one side around a connecting shaft under the effect of elastic pieces, an included angle formed by the bent self-folding hook piece and a tail rod is a right angle, the chest wall or the abdominal wall is jointly clamped by the right-angle structure and the hoop assembly from inside and outside, the puncture fixing device is accordingly fixed, and the laparoscope puncture device or other working pieces is/are further fixed. The puncture fixing device has the advantages of being easy to operate, flexible in use, small in fixing area and reliable in fixation.

Description

A kind of puncture fixator

Technical field

This utility model belongs to medical apparatus and instruments appurtenance field, relates in particular to the fixedly puncture fixator of use of a kind of laparoscope puncture outfit.

Background technology

Modern surgery Wicresoft chamber mirror technology is very ripe, especially at abdominal surgery, is widely used, and various operating apparatuss and supervision camera lens all need to introduce body cavity through chamber mirror perforator; During clinical practice, according to the chamber mirror perforator that need to select different size, diameter of patient body state and operation, puncture, puncture Effect of Back-Cavity Mirror perforator conventionally all can move and even skid off in operating process, and then the placement of need to again puncturing, like this operation progress and quality are all large impact; For head it off, conventional fixing means has artificial chucking method, outer housing fixed mount method, mounting method, epidermis suture needle method etc. at present; These methods or stationary plane are greatly or very not firmly or bring derivative wound to patient.

Utility model content

In order to address the above problem, this utility model discloses the fixedly puncture fixator of use of a kind of laparoscope puncture outfit.

This utility model is created the technical scheme adopting: a kind of puncture fixator, comprise: guide, certainly roll over hook, hoop component, guide is the pointed strip of head end or elongate tubular, from folding hook, it is strip, from the energy slip bonded to each other of folding hook and guide or certainly roll over hook and can insert in guide and slide, when certainly rolling over hook and guide relative sliding to certain position, from the rolled over section of folding hook because of the effect of elastic component can be to a side around connecting axle bending, after bending with the rectangular shape of angle of foot piece formation.

In such scheme, certainly roll over hook and comprise: foot piece, can the section of folding; Two anchor points are arranged at foot piece bottom, to facilitate the indication that can the section of folding struts, closes up with fixing; Can the section of folding can be multi-clove type, like this, when can the section of folding strutting, can hook fixing in a plurality of angles; Can the section of folding can be two-period form, have two pin joints on it, pin joint is all equipped with elastic component, when certainly rolling over hook and guide relative sliding, the bending respectively of first, second pin joint, can the section of folding after bending and foot piece at right angles hook-shaped.

In such scheme, hoop component has two anchor ears, the adjustment screw that these two anchor ears are all useful on locking or unclamp, and one of them anchor ear is for locking or unclamping from rolling over hook, and another anchor ear is for locking or unclamp work package.

The beneficial effects of the utility model are: simple to operate, use flexibly, fixed-area is little and fixing reliable.

Accompanying drawing explanation

Fig. 1 is this utility model schematic diagram while closing up with elongate tubular guide.

Fig. 2 is this utility model schematic diagram while strutting with elongate tubular guide.

Fig. 3 is this utility model schematic diagram while closing up by elongate guide.

Fig. 4 is this utility model schematic diagram while strutting by elongate guide.

In accompanying drawing: certainly rolling over hook can the section of folding 1, hoop component chute 2, hoop component 3, guide 4, closes up anchor point 5, struts anchor point 6, certainly rolls over hook foot piece 7, work package 8, outer housing hoop 11.

The specific embodiment

In description of the present utility model, it will be appreciated that: term " certainly roll over hook can the section of folding ", " hoop component chute ", " hoop component ", " guide ", " closing up anchor point ", " strutting anchor point ", " certainly rolling over hook foot piece ", " work package ", " outer housing hoop ", " elongate tubular ", " strip ", " elastic component " etc., just for convenience of description with explain this utility model, and can not be interpreted as restriction of the present utility model.

This utility model is made of stainless steel material, is about 120mm, the about 6mm of diameter or width, thick about 3mm when by elongate guide; Guide 4 is except the effect of guiding, also to constraint effect from folding hook can the whether bending of the section of folding 1; Elastic component that can the section of folding 1 hinged place from folding hook is generally spring or flexure strip, and certainly rolling over hook can the section of folding 1 also can have and be convenient to hook stable salient point; In order to coordinate the work package of different size, caliber, the outer hoop of hoop component is generally replaceable hoop, for the ease of adjusting the screw on hoop component 3, is conventionally also furnished with special screwdriver.

With reference to each accompanying drawing, this utility model can Reusability through cleaning, after sterilization, during use, closing up anchor point 5 first locates, at this moment from rolling over that hook can the section of folding 1 be inserted in guide 4 or concordant with guide 4, after capturing position, because guide 4 head ends are sharp, just can directly insert patient chest, abdominal cavity; After insertion to strutting well anchor point 6, now, certainly roll over hook can the section of folding 1 because losing the constraint of guide 4, from folding hook, can under the counteracting force of the section of folding 1 at elastic component, strut, and then hook cavity wall, now if any a plurality of sections of folding, just can strut and hook cavity wall from a plurality of angles; When certainly rolling over hook, can the section of folding 1 strut and hook after cavity wall, just removable hoop component 3 is to patient's epidermis place, to cavity wall, compress again fixedly hoop component 3 screwings a little, make hoop component 3 and certainly roll over hook phase banding, thereby make hoop component 3 and can live thoracic wall or stomach wall by the common clip of the section of folding 1 " inside and outside " from rolling over hook, so far, this utility model just fixes on patient chest or abdominal part, finally, work package 8 is fixed in the outer hoop of hoop component 3, adjust after the degree of depth, screw outer hoop screw, can stablize regular worker's workpiece 8.

When needs take out this utility model, after work package 8 is taken out, unclamp the screw on hoop component 3, slide from rolling over hook foot piece 7 or guide 4 to closing up well anchor point 5, now from roll over hook can the section of folding 1 because of the constraint of guide 4 and then close up into strip always, so far, just can take out this utility model.

Enforcement of the present utility model is not limited to above embodiment, is also not limited to fixedly use of laparoscope puncture outfit during clinical practice, all with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
