The present invention relates to a kind of electronic tissue holding forceps, it includes clamp fixator, rotatable shaft, steel wire, power set, handle, clamp controller and Rotation Controllers.Clamp fixator is fixing with rotatable shaft to be connected, and rotatable shaft is connected with power set by steel wire, and the power set other end is connected with handle, and the outside of power set is provided with clamp controller, and power set electrically connect with Rotation Controllers.Power set include miniature progressive motor and power transmission shaft；Miniature progressive motor electrically connects with Rotation Controllers, and miniature progressive motor is connected with steel wire by power transmission shaft.Clamp fixator uses tiny dentalation.Micro-step motor can select external power supply or battery to power.Electronic tissue holding forceps can arrive internal by the pipeline treated outside pipeline or scope of two-chamber scope.The present invention can assist the destination organization mentioning needs excision, fully exposes incisxal edge, reduces operating difficulty and the risk of complication generation.

Description

A kind of electronic tissue holding forceps

Technical field

The present invention relates to a kind of medical apparatus and instruments, especially with regard to a kind of electricity assisting use under endoscopic mucosal in excision Dynamic tissue holding forceps.

Background technology

Under endoscopic mucosal, the main electric knife in a variety of manners of excision (ESD) is main, and the purpose updating electric knife is In order to excise pathological changes faster, stop blooding and avoid perforation.But, no matter use which kind of electric knife, excision pathological changes, avoid perforation and Carrying out hemostasis operation, surgical field of view is all by necessary to ESD clearly.In practical operation, major part complication is all In the case of the visual field is unsatisfied, blindness operation causes.It addition, surgical field of view exposes dissatisfied, doctor dare not operate, It it is the major reason of operating time prolongation.

At present, the technological means exposing surgical field of view is the most limited, mainly by being enclosed within hyaline cap and the tune of scope head end Whole patient body position, uses gravity to expose surgical field of view, and this needs experienced human users, the operating technology requirement to doctor Height, and be not can to reach the satisfied visual field to expose.Which prevent under endoscopic mucosal excision in clinic, particularly basic unit The application of hospital.

Summary of the invention

For the problems referred to above, it is an object of the invention to provide a kind of electronic tissue holding forceps, it can mention needs excision Destination organization, fully exposes incisxal edge, reduces operating difficulty and the risk of complication generation.

For achieving the above object, the present invention takes techniques below scheme: a kind of electronic tissue holding forceps, it is characterised in that it Including clamp fixator, rotatable shaft, steel wire, power set, handle, clamp controller and Rotation Controllers；Described clamp is solid Determining that device and described rotatable shaft are fixing to be connected, described rotatable shaft is connected with described power set by described steel wire, described moves The power apparatus other end is connected with described handle, and the outside of described power set is provided with described clamp controller, and described power fills Put and electrically connect with described Rotation Controllers.

Preferably, described power set include miniature progressive motor and power transmission shaft；Described miniature progressive motor and described rotation Transcoder controller electrically connects, and described miniature progressive motor is connected with described steel wire by described power transmission shaft.

Preferably, described micro-step motor uses external power supply or battery to power.

Preferably, described clamp fixator uses dentalation.

Preferably, described electronic tissue holding forceps can arrive body by the pipeline treated outside pipeline or scope of two-chamber scope In.

Due to the fact that and take above technical scheme, it has the advantage that 1, the present invention uses electronic tissue holding forceps, The clamp fixator anglec of rotation and speed are controlled, it is to avoid what machinery rotated can not be handling.2, the present invention uses electronic tissue handle Hold pincers, reduce operating difficulty, fully expose incisxal edge, improve the operation visual field.3, the present invention uses clamp fixator, with destination organization Contact surface more closely sealed, the damage to destination organization is less.

Accompanying drawing explanation

Fig. 1 is the electronic tissue holding forceps overall structure schematic diagram of the present invention；

Detailed description of the invention

With embodiment, the present invention is described in detail below in conjunction with the accompanying drawings.

As it is shown in figure 1, the present invention provides a kind of electronic tissue holding forceps, it includes clamp fixator 1, rotatable shaft 2, steel Silk 3, power set 4, handle 5, clamp controller 6 and Rotation Controllers.Clamp fixator 1 is fixing with rotatable shaft 2 to be connected, can Rotary shaft 2 is connected with power set 4 by steel wire 3, and power set 4 other end is connected with handle 5, and the outside of power set 4 sets Being equipped with clamp controller 6, for controlling the folding of clamp fixator 1, power set 4 electrically connect with Rotation Controllers, by rotating Controller controls the rotating speed of power set 4, and then controls rotating speed and the angle of rotatable shaft 2.

In above-described embodiment, power set 4 include miniature progressive motor and power transmission shaft.Miniature progressive motor and Spin Control Device electrically connects, and for controlling the duty of miniature progressive motor, miniature progressive motor is connected with steel wire 3 by power transmission shaft.

In the various embodiments described above, clamp fixator 1 uses tiny dentalation, more closely sealed with the contact surface of destination organization, Damage to destination organization is less, and the stability of clamp fixator 1 is strong, the superior function of zero dislocation, possesses 90 ° of side rotating functions, Expand clinical tissue target zone, especially improve the difficulty of the clamp at position such as at the bottom of esophagus, intestinal sidewall, stomach.

In the various embodiments described above, micro-step motor can select external power supply or battery to power.

In the various embodiments described above, electronic tissue holding forceps can be by the pipe treated outside pipeline or scope of two-chamber scope Road arrives internal.

Based on said apparatus, the present invention also provides for the using method of a kind of electronic tissue holding forceps, and it specifically comprises the following steps that

1) lateral edges of initial gross separation destination organization under scope；

2) control clamp fixator by clamp controller and clamp the edge of destination organization；

3) combine endoscopic views destination organization, and by the rotary speed of Rotation Controllers control micro-step motor, enter And controlling rotary speed and the angle of clamp fixator, destination organization is rolled the most at last；

4) fully give away one's position the incisxal edge of tissue, then peels off destination organization with electric knife.

The various embodiments described above are merely to illustrate the present invention, the structure of each parts, size, arrange position and shape is all permissible Be varied from, on the basis of technical solution of the present invention, all improvement individual part carried out according to the principle of the invention and etc. With conversion, the most should not get rid of outside protection scope of the present invention.
