Description

Technical Field

[0001] The invention belongs to the technical field of blood vessel ligation, and in particular relates to a blood vessel ligation wire feeder during surgery. Background Art

[0002] During the operation, the doctor usually ligates the blood vessels by using a vascular clamp to wrap the ligature around the delivery line, so as to achieve the purpose of bypassing the blood vessel to be ligated first, and then lead it out for further knotting after bypassing the target blood vessel, and finally tighten the target blood vessel.

[0003] The above operation has the following problems: Due to the complex nerves and blood vessels at the surgical site, especially for ligating blood vessels with small incisions and deep tissues, it is difficult to operate the vascular clamp around the wire in a small space, and it is even more difficult for deep tissues. In view of the difficulty in ligating the target blood vessels, the medical instruments used in the operation are sometimes unable to deliver the ligature to the target blood vessel, let alone bypass the target blood vessel, which leads to the entire operation time being extended, and even unnecessary blood loss due to the failure to ligate the blood vessels in time. Summary of the invention

[0004] The purpose of the present invention is to provide an intraoperative vascular ligation wire feeder, which greatly improves the efficiency of intraoperative wire feeding. The purpose of wire winding can be achieved through only a closing action of the wire feeder, and for the ligation of deep tissue blood vessels, it solves a long-standing major problem of wire feeding difficulties.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A wire feeder for intraoperative vascular ligation comprises a clamp body, which is hinged by a first clamp arm and a second clamp arm, the front end of the first clamp arm is a first clamp head, and a protrusion is provided on the groove of the first clamp head, the front end of the second clamp arm is a second clamp head, and an insert is provided on the groove of the second clamp head, a wire feeder is provided between the first clamp head and the second clamp head, and the wire feeder is composed of an upper clamp body and a lower clamp body, the upper clamp body and the lower clamp body are connected by a double torsion spring, the upper and lower surfaces of the right ends of the upper and lower clamp bodies are provided with grooves, the insert of the second clamp head is embedded in the notch of the wire feeder, the protrusion on the first clamp head is engaged with the groove at the right end of the clamp body, and the ligature is wrapped around the wire feeder.

[0007] Preferably, the upper clamping body and the lower clamping body are provided with through holes, and the two bent legs of the double torsion spring are respectively placed in the through holes of the upper clamping body and the lower clamping body.

[0008] Preferably, the plug-in is spherical, the left ends of the upper clamp body and the lower clamp body are hemispherical, and the upper clamp body and the lower clamp body can be contained in the spherical plug-in after being combined.

[0009] Preferably, the binding wire can be wound around the upper clamp body or the lower clamp body.

[0010] Preferably, a wire tying post is provided on the upper clamp body or the lower clamp body for tying the binding wire.

[0011] Preferably, the end faces formed at the right ends of the upper clamp body and the lower clamp body are consistent with the shape of the groove surface of the first clamp head.

[0012] The above technical solution can achieve the following beneficial effects:

[0013] The present invention uses a wire clamp to deliver the wire from one end of the clamp body to the other end, and cooperates with the closing action of the clamp body to bypass the target blood vessel and then lead it out of the body. The whole process is simple and convenient to operate, and the purpose of wire delivery can be achieved. It is suitable for use by surgeons and is worthy of promotion and application in surgical operations.

[0022] The present invention will be further described below in conjunction with the accompanying drawings:

[0023] like Figure 1-5As shown, a wire feeder for intraoperative vascular ligation includes a clamp body, which is hinged by a first clamp arm 3 and a second clamp arm 2. The front end of the first clamp arm 3 is a first clamp head 6, and a protrusion 12 is provided on the groove of the first clamp head 6. The front end of the second clamp arm 2 is a second clamp head 4, and an insert 14 is provided on the groove of the second clamp head 4. A wire feeder 5 is provided between the first clamp head 6 and the second clamp head 4. The wire feeder 5 is composed of an upper clamp body 7 and a lower clamp body 8. The upper clamp body 7 and the lower clamp body 8 are connected by a double torsion spring 9. The upper and lower surfaces of the right ends of the upper clamp body 7 and the lower clamp body 8 are provided with grooves 13. The insert 14 of the second clamp head 4 is embedded in the notch of the wire feeder 5. The protrusion 12 on the first clamp head 6 is clamped with the groove 13 at the right end of the clamp body 8, and the wire is wrapped around the wire feeder 5. The upper clamp body 7 and the lower clamp body 8 are provided with a through hole 10, and the two bent legs 11 of the double torsion spring 9 are respectively placed in the through holes 10 of the upper clamp body 7 and the lower clamp body 8. The plug-in 14 is spherical, and the left ends of the upper clamp body 7 and the lower clamp body 8 are hemispherical. After the upper clamp body 7 and the lower clamp body 8 are combined, they can be contained in the spherical plug-in 14. The binding wire can be wound around the upper clamp body or the lower clamp body. The upper clamp body or the lower clamp body is provided with a wire tying column for tying the binding wire. The end surface formed at the right end of the upper clamp body 7 and the lower clamp body 8 is consistent with the shape of the groove surface of the first clamp head 6.

[0024] Example:

[0025] During use, the binding wire is wound around the upper clamp body 7 or the lower clamp body 8, specifically around the left end of the clamp body, and the left end of the wire feeder 5 is opened and contained on the plug-in 14 of the second clamp head 4 ( Figure 3 As shown in the figure, the doctor holds the handle 1 of the clamp body and inserts the entire clamp body into the surgical exposed tissue. After determining the target blood vessel, the clamp head is placed behind the target blood vessel and the clamp body is closed so that the first clamp head 6 contacts the second clamp head 4. At this time, the right end face of the wire feeder 5 touches the edge of the protrusion 12 on the first clamp head 6. Under the pressure of the clamp body ( Figure 4 As shown in the figure, the right end of the wire feeder 5 presses the upper and lower clamps to cause the left end of the wire feeder 5 to open, and then detach from the second clamp head 4. At the same time, the groove at the right end of the wire feeder 5 is stuck on the protrusion 12 ( Figure 5 As shown in the figure, the ligature has now passed around the target blood vessel. Move the clamp forward (towards the doctor) to lead the ligature out to the doctor.

[0026] A wire tying pole can be installed on the clamp body of the present invention, which can facilitate wire winding. At the same time, the plug-in 14 of the second clamp head 4 specifically adopts a spherical structure, which is convenient for clamping. At the same time, the shape of the notch at the left end of the wire feeder 5 is consistent with the spherical plug-in 14, wherein the grooves 13 on the upper and lower surfaces of the right end of the wire feeder 5 are hemispherical, and its shape is consistent with the shape of the protrusion 12 on the groove of the clamp head 6.

[0027] The upper and lower clamps of the present invention are specifically hinged by a double torsion spring 9, wherein two bent legs 11 of the double torsion spring 9 are respectively placed in the through holes 10 of the upper clamp 7 and the lower clamp 8, so that the left end of the wire feeder is in a normally closed state.

[0028] The above are all preferred embodiments of the present invention. For ordinary technicians in this technical field, without departing from the principle of the present invention, various equivalent modifications to the present invention belong to the protection scope of the claims attached to this application.
