The handle is connected with the clamping section by the connecting section, the handle is also connected with the stripper, and an operator firstly uses the stripper to strip the blood vessel or the nerve. After the stripping is finished, the suture is sent into the clamping section to be clamped, the vertical direction of the suture sending stripper is turned, an operator still holds the handle, the suture is sent to the blood vessel or nerve to be constricted or ligated by using the clamping section, and the operator then narrows or ligates the blood vessel or nerve after the stripping by using the suture. The wire feeding stripper can complete stripping and wire feeding operation, and improve the operation efficiency.

Further, the clamping section comprises a bending section, the bending section is connected to the connecting section, and a clamping seam used for clamping the suture line is arranged on the bending section.

The setting of bending segment more does benefit to and carries out the centre gripping to the suture, can also ensure simultaneously with the suture centre gripping in a certain position within range of sending the line portion, the different operators of being convenient for send the line operation.

Furthermore, the bending section is provided with a clamping groove for clamping a blood vessel or a nerve. The clamping groove is used for clamping the blood vessel or nerve to be constricted or ligated, so that the blood vessel or nerve can be pulled to a certain extent, the reliability of constriction or ligation is improved, and constriction or ligation is facilitated.

Furthermore, the clamping section still includes the perforation section, and the perforation section sets up in the one end of keeping away from the linkage segment of buckling section, and the perforation section is formed with the through-hole, through-hole and centre gripping seam intercommunication.

Referring to fig. 1 and 2, an embodiment of the present application provides a wire feeding stripper 100, which includes a wire feeding portion 200, a handle 300, and a stripper 400. When performing an operation using the wire feeding detacher 100, the operator holds the handle 300, first, the detacher 400 is directed downward, and the detacher 400 is used to perform an operation of detaching a blood vessel or a nerve. After the blood vessel or nerve is detached, the operator places the suture thread on the thread feeding part 200, feeds the suture thread to the detached blood vessel or nerve using the thread feeding part 200, and narrows or ligates the blood vessel or nerve.

In the embodiment of the present application, the wire feeding portion 200 has a connecting section 210 and a clamping section 220 for clamping the suture 240, the connecting section 210 is fixed to an end of the handle 300 away from the clamping section 220, and the stripper 400 is fixed to an end of the handle 300 away from the connecting section 210.

An operator holds the handle 300, uses the stripper 400 to strip the blood vessel or nerve, then sends the suture line into the clamping section 220 for clamping, and after the up-and-down direction of the wire feeding stripper 100 is turned, the operator still holds the handle 300, and uses the clamping section 220 to send the suture line to the blood vessel or nerve to be narrowed or ligated for narrowing or ligation operation. The wire feeding stripper 100 provided by the embodiment can complete stripping and wire feeding operations, thereby improving the operation efficiency.

In this embodiment, in order to facilitate the dissection of blood vessels or nerves, the extending direction of the dissector 400 away from the handle 300 is set to be at an angle of 110 ° to 140 ° with respect to the axis of the handle 300, and optionally, the angle may be 110 °, 120 °, 130 ° or 140 °. By the arrangement, when stripping blood vessels or nerves, an operator holds the handle 300 by hand, and can adjust the stripping element 400 at multiple angles by only slightly adjusting the angle of the handle 300, so that the stripping operation is completed.

In order to facilitate the peeling operation, the peeling unit 400 is further configured such that the thickness thereof gradually decreases in a direction away from the handle 300, and the surface thereof close to the handle 300 is configured to be a concave-convex surface. Specifically, the surface of the detacher 400 near the handle 300 is provided in a stripe or grid pattern.

When the dissector 400 is used to dissect a blood vessel or nerve, the end of the dissector 400 away from the handle 300 with the smaller thickness first contacts the tissue around the blood vessel or nerve, and the dissector 400 is more likely to extend into the gap between the blood vessel or nerve and the tissue. In the stripping process, the friction force between the concave-convex surface and tissues and blood vessels or nerves is increased, so that the blood vessels or the nerves are stripped more stably and reliably, and the stripping operation is more convenient.

In general, in the process of performing blood vessel or nerve dissection, even if an operator is experienced and operates properly, bleeding is difficult to avoid, or in the case that physiological saline needs to be used for flushing tissues around the blood vessel or nerve, the blood vessel or nerve is covered by the blood or physiological saline, and dissection of the operator is hindered. Based on this, the wire feeding stripper 100 provided in the present embodiment is further provided with a liquid suction function. With continued reference to fig. 1 and 2, the stripper 400 is provided with a suction port 410, the handle 300 is provided with a negative pressure port 310, and the suction port 410 and the negative pressure port 310 are communicated with the inside of the handle 300 inside the stripper 400.

Before an operation, the negative pressure interface 310 is connected with a negative pressure suction device, in the stripping process, when blood or/and physiological saline and the like need to be sucked, the negative pressure suction device is started, the blood, the washed physiological saline and the like can be sucked out through the suction port 410 on the stripper 400, the interior of the handle 300 and the negative pressure interface 310 in sequence, and the liquid suction can be realized while stripping, so that the operation visual field is clear, and the operation safety is improved.

In order to timely suck blood and/or physiological saline, the suction port 410 is provided at one end of the sheath 400 away from the handle 300.

In other embodiments, the suction port 410 may also be provided elsewhere on the detacher 400.

When the peeling operation is performed, liquid such as blood adheres to the handle 300, which increases the difficulty of the operator in holding the handle. In order to make the operator hold the handle 300 more firmly, the outer wall of the holding section of the handle 300 is provided with a cross-hatched structure or/and a hand groove structure, so that the friction force between the handle 300 and the fingers of the operator is increased, and the handle 300 is held more firmly.

Of course, in other embodiments, the webbing may also cover the entire outer wall of the handle 300.

After the vessel or nerve is completely peeled and clearly appears in the visual field, the suture thread feeding operation is required to be carried out next, the suture thread is clamped on the clamping section 220, the thread feeding part 200 is turned to the lower part, the suture thread is fed to the vessel or nerve which is completely peeled, and then the constriction or ligation of the vessel or nerve is carried out.

Referring to fig. 1 and 2, in the present embodiment, the wire feeding portion 200 is formed by two identical stainless steel strip-shaped members contacting and parallel to each other, and the clamping portion 220 is a section of the two strip-shaped members, and the specific position thereof can be determined by an operator according to the depth of the blood vessel or nerve to be fed.

In this embodiment, the clamping slot 240 is actually the contact gap between the clamping segments 220 of the two rails.

After clamping the suture to the clamping seam 240, the suture is pulled to the bending section 230, and the bending section 230 is arranged, so that the suture can be clamped, and the suture can be clamped in a certain position range of the thread feeding part 200, and different operators can conveniently carry out thread feeding operation.

In other embodiments, the lengths of the two strips forming the wire feeder 200 may be different, so long as the strips of the gripping section 220 abut against each other to form the gripping seam 240.

In other embodiments, three, four, or other numbers of bars may be provided. When the strip-shaped member sets up three, three strip-shaped member can contact the parallel setting, forms two parallel centre gripping seam 240, and centre gripping section 220 is exactly the certain section of two parallel centre gripping seams 240, when needing two stylolite simultaneously, with two stylolite centre gripping respectively in the certain section of two parallel centre gripping seams 240, of course, under this condition, also can only use a centre gripping seam 240 centre gripping a stylolite. When the number of the strip-shaped members is other than the above-mentioned number, the holding slit 240 is formed similarly to the holding of the suture thread.

In other embodiments, three or more than three strips can be arranged in contact with each other, and at the same time, the number of formed clamping seams 240 is correspondingly increased, and the number of sutures which can be clamped at one time is also increased. The number of the specific strip-shaped members and the arrangement mode can be determined according to the maximum thread feeding amount.

With continued reference to fig. 1 and 2, in order to facilitate the holding of the suture, the holding section 220 further includes a perforation section 250, the perforation section 250 is disposed at an end of the bending section 230 away from the connecting section 210, the perforation section 250 is formed with a through hole 251, and the through hole 251 is communicated with the holding slit 240. In this embodiment, the perforated section 250 is actually a ring formed by two strips separated and surrounded at the end away from the handle 300. The suture is passed through the through-hole 251 and then pulled to the clamping section 220, completing the clamping of the suture.

In order to facilitate the constriction or ligation of the blood vessel or nerve, the bending section 230 is formed with a groove for clamping the blood vessel or nerve, and the groove is trapezoidal or arc-shaped. The clamping groove is used for clamping the blood vessel or nerve to be constricted or ligated, so that the blood vessel or nerve can be drawn to a certain extent, and the constriction or ligation reliability is improved.
