Description

Continuous clip applier

Technical Field

The utility model belongs to the technical field of surgical instruments, and particularly relates to a continuous clip applier.

Background

In clinical medicine, a ligation clip is a ligation of a blood vessel or other tubular structure suitable for use in a clinical laparoscopic procedure or a surgical non-absorbable ligation clip. In the operation process, clear blood vessels need to be dissociated firstly, then the ligation clamps are clamped by the clamp applying forceps to close the blood vessels, and finally the blood vessels are separated.

The above-mentioned methods are widely used in the existing clinical operation, but the clip applier still has certain flaws, specifically:

(1) the traditional clip applier can only clamp one ligation clip at a time, the clip applier needs to be taken out of a human body after the ligation clip is closed, and the next ligation clip is clamped and extends into the human body to be operated.

(2) The repeated removal of the clip from the clip holder with the clip applier wastes time and reduces the efficiency of the procedure.

(3) When the clamp is taken out and the human body stretches into the clamp again, the last closed position needs to be found, certain time needs to be spent, and the operation efficiency is reduced.

(4) When a single vascular clamp has poor closing effect and risks of tissue and vascular bleeding or the like, secondary closing cannot be adopted in time.

the front section part in the inner tube is provided with a filling bin for filling the ligature clamp, and the rear section part in the inner tube is provided with an automatic ligature clamp pushing mechanism.

As a preferred technical scheme, the rotating assembly comprises a central rotating sleeve, and a control roller is sleeved outside the central rotating sleeve.

As a preferred technical scheme, the locking structure comprises a clamping groove correspondingly formed in the handle shell and the central rotating sleeve, and a clamping piece is inserted in the clamping groove in a matched manner.

According to the preferable technical scheme, the automatic pushing mechanism of the ligation clip comprises a push plate extending to the filling bin, the push plate is connected with a pull rod, the outer end of the pull rod penetrates through the inner tube push block, and a pushing spring is sleeved on the pull rod.

As a preferred technical scheme, a pull rod handle is installed at the outer end of the pull rod.

Due to the adoption of the technical scheme, the utility model has at least the following beneficial effects:

(1) fill the feed bin in the pincers of executing and can load a plurality of ligature clamps, press from both sides automatic pushing mechanism through the ligature and can release one by one, realize executing in succession and press from both sides, do benefit to and improve operation efficiency.

(2) When the forceps head is opened after the forceps is used, the next ligation clip can be automatically filled to the position of the forceps head, the using mode of the forceps head is consistent with that of a traditional forceps head, the operation and the use are convenient, and the surgical adaptability is good.

(3) The pull rod is pulled backwards when the filling bin is assembled, so that enough space can be provided for the filling bin, and 6 ligation clamps can be filled at most.

Detailed Description

The utility model is further illustrated below with reference to the figures and examples. In the following detailed description, certain exemplary embodiments of the present invention are described by way of illustration only. Needless to say, a person skilled in the art realizes that the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

As shown in fig. 1 and 2, the continuous clip applier comprises a handle 1, a wrench 2, an upper binding clip 3 and a lower binding clip 4, wherein the upper binding clip 3 and the lower binding clip 4 are closed ligation clip components, the handle 1 is hinged to the wrench 2, and the handle 1 and the wrench 2 are matched to control the binding clip to be closed.

A rotating assembly is arranged in the handle 1, and a locking structure is arranged between the handle 1 and the rotating assembly; the rotating assembly is connected with an outer pipe 7, and the outer pipe 7 is connected with the upper tong head 3; in this embodiment, the rotating assembly includes a central rotating sleeve 51, a control roller 52 is sleeved outside the central rotating sleeve 51, and the control roller 52 is rotated to control the rotation of the tong head; the locking structure comprises a clamping groove 61 correspondingly formed in the shell of the handle 1 and the central rotating sleeve 51, a clamping piece 62 is inserted in the clamping groove 61 in a matched mode, and the rotating assembly in the handle can be fixed through the clamping piece 62.
