Abstract

The utility model discloses a stretchable electric hook which comprises a hook head, a hook body and a hook handle in turn from end to tail, wherein the hook body is formed by mutually nesting two concentric circular tubes of a first hook body and a second hook body in turn from outside to inside; the tail of the first hook body is fixedly connected with the hook handle; a first limiting slot is arranged on the first hook body along axial direction; a first limiting lug boss is arranged at the tail of the second hook body; the first limiting lug boss is slidably arranged in the first limiting slot; a first limiting bolt is arranged on the first limiting lug boss; and the end part of the second hook body is fixedly connected with the hook head. The length of the stretchable electric hook is conveniently and manually adjusted according to the depth of an operated part.

Description

A kind of scalable electric hook

Technical field

This utility model belongs to medical instruments field, and is particularly related to a kind of electric hook that can stretch, regulate length.

Background technology

Wicresoft's endoscope-assistant surgery is the surgery Development Trend, and it is littler than traditional surgical operation to disorganization, can shorten average stay, alleviates the pain that operation brings to the patient, and patient's post-operative recovery is also very fast.Electricity is hooked in one of apparatus that frequency of utilization is the highest in the endoscope-assistant surgery; In the operation of electric coagulation hemostasis, separate tissue, bringing into play irreplaceable effect; But the tissue electricity hook that runs into the deep through regular meeting can't touch or the tissue nearer apart from skin; The electricity hook dislikes oversize again, the problem of inconvenient operation.The electric hook length of clinical practice at present is uncontrollable, often need be according to the operation technique of different parts and the electric hook of frequent change different size has not only delayed operating time but also increased the probability that pollutes in the art.

Summary of the invention

Can not be in order to overcome existing electric hook according to the depth and the defective of regulated at will length of tissue; This utility model provides a kind of scalable electric hook; This electricity hook has not only kept the advantage of original electric hook hemostasis, free tissue, and can be easily according to its length of depth regulated at will of organizing.

The technical scheme of this utility model: a kind of scalable electric hook; Constitute by gib head, coupler body and the neck of hook successively to afterbody by the end; By the concentric pipe of two of first coupler body and second coupler bodies mutually nested composition, the afterbody of first coupler body is fixedly connected with the neck of hook coupler body ecto-entad successively, and the first coupler body upper edge is axially arranged with first stopper slot; The afterbody of second coupler body is provided with first spacing block set; First spacing block set slides and is located in first stopper slot, on first spacing block set, is provided with first caging bolt, and the end of second coupler body is fixedly connected with gib head.

Described scalable electric hook also is provided with the smoking flexible pipe, and the smoking flexible pipe passes in the through hole of the neck of hook by running through whole scalable electric hook in second coupler body, and the smoking flexible pipe is connected with negative pressure air-suction device.

The diameter of first coupler body is 4 ~ 7mm.

The length of first coupler body is 10 ~ 18cm.

The neck of hook is provided with gauge tap, and the neck of hook is connected with power supply.

Beneficial effect

1. the electric hook of this utility model is easy to use;

2. the electric hook of this utility model can use repeatedly;

3. the scalable electric hook of this utility model is applicable to the tissue of the different depths, and is easy to adjust, saved the operating time of changing apparatus;

4. the scalable electric hook of this utility model has been avoided the electric hook of frequent change different size and pollution problem in the art brought.

5. the scalable electric hook of this utility model is provided with smoking apparatus, the interference of flue gas in can avoiding performing the operation.

Description of drawings

Fig. 1 is a kind of embodiment of this utility model.

Fig. 2 is the another kind of preferred implementation of this utility model.

1 is the neck of hook among the figure, and 2 is coupler body, and 2-1 is first coupler body, and 2-2 is second coupler body, and 3 is gib head, and 4 is first stopper slot, and 5 is first caging bolt, and 6 are the smoking flexible pipe, and 7 is the negative pressure smoke device.

The specific embodiment

Further explain below in conjunction with 1 pair of this utility model of accompanying drawing.

A kind of scalable electric hook; Constitute by gib head 3, coupler body 2 and the neck of hook 1 successively to afterbody by the end; By the concentric pipe of two of the first coupler body 2-1 and the second coupler body 2-2 mutually nested composition, the afterbody of the first coupler body 2-1 is fixedly connected with the neck of hook 1 coupler body 2 ecto-entads successively, and the first coupler body 2-1 upper edge is axially arranged with first stopper slot 4; The afterbody of the second coupler body 2-2 is provided with first spacing block set; First spacing block set slides and is located in first stopper slot, and the end that on first spacing block set, is provided with first caging bolt, 5, the second coupler body 2-2 is fixedly connected with gib head 3.Degree of tightness through regulating the one the second caging bolts is carried out spacing.Caging bolt is unscrewed, second coupler body is slided into suitable position, and then tighten in the caging bolt operation and just can regulate the length of electric hook very easily.

A kind of preferred version is to be equipped with smoking flexible pipe 6 again, and smoking flexible pipe 6 passes in the through hole of the neck of hook 1 by running through whole scalable electric hook in the second coupler body 2-2 then, and smoking flexible pipe 6 is connected with negative pressure air-suction device 7.In the operation through negative pressure air-suction device with the flue gas that produces by extracting out in the smoking flexible pipe 6, can avoid the interference of flue gas to operation.

The diameter of the first coupler body 2-1 is 4 ~ 7mm.The diameter of second coupler body is slightly less than first coupler body.The diameter of smoking flexible pipe is minimum.

The length of the first coupler body 2-1 is 10 ~ 18cm.

The neck of hook 1 is provided with gauge tap, and the neck of hook 1 is connected with power supply.

Be provided with a seal wire in the whole electric hook device, its length can not be less than the length under the electric hook full extension state.Scalable electric hook is except gib head, and the surface of remainder is all with insulation, heat-barrier material.

When using this scalable electric hook to undergo surgery operation, the tissue nearer apart from skin can only use first coupler body, and long 15cm can reach requirements of operation, and deep tissue can be pulled out second coupler body to satisfy the operation demand.If in the time of need electric hook being shortened, can it be regained through regulating caging bolt.
