Description

Operating forceps with knot pushing function

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an operating forceps with a knot pushing function.

Background

In a minimally invasive surgical procedure, a wound of an organ operated in an abdominal or thoracic cavity is sutured, and a suture thread is tied at a distal end of the sutured wound to prevent the suture thread from being loosened from the wound of the sutured organ. The existing method for knotting the chest cavity and the abdominal cavity comprises the steps of firstly knotting in vitro, wherein a doctor holds one end of a suture line with one hand, clamps the other end of the suture line with an operating forceps and makes a loose knot on the suture line in the hand, then the doctor needs to put down the operating forceps, takes up a knotting device, uses a knot pusher to hang the knot and pushes the knot to an operating knife opening in the cavity, and then locks the knot. The knotting by the method has the disadvantages that medical instruments need to be replaced, the operation speed is slowed, and the operation time is prolonged.

Moreover, the structure and the use principle of various thoracoscope knot pushers determine that the two ends of a suture held by the left hand must be tensioned in the whole process of pushing and fastening a knotted thread; the result is awkward manipulation and easy disturbance of the first knot when the second knot is tied, resulting in loosening of the knot and failure of the ligation.

The common operation forceps with tooth sockets are used as a knot pusher to finish deep ligation, so that the defects can be overcome. However, the conventional forceps cannot be smoothly inserted into a small micro-incision or a puncture cannula hole of the thoracoscope operation and opened and closed in the thoracic cavity, so that the deep ligation operation of the thoracoscope operation cannot be completed.

Accordingly, there is a need in the art for a surgical clamp with a push knot function that eliminates or at least alleviates some or all of the above-mentioned deficiencies of the prior art.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the utility model, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

In this context, when expressing orientation, it is common to refer to the instrument operator as being relatively close to the instrument operator as the "proximal end" and relatively far from the instrument operator as the "distal end". Further, the length direction of the forceps may be referred to herein as the axial direction.

Referring to fig. 1, there is shown a general schematic view of the forceps of the present invention. In the utility model, the surgical forceps comprise a forceps head 1, a forceps body 2, an adjusting part 3, a finger-covering ring handle 41 and a finger-covering ring handle 42. The forceps head 1 is made into a curved arc shape. The finger ring handle 41 and the finger ring handle 42 are provided with a fixed latch 51 and a fixed latch 52, respectively. The forceps head 1 is connected with the forceps body 2, and the forceps head 1 can be opened and closed towards two sides under the control of the finger-covering ring handle 41 and the finger-covering ring handle 42 through the action of the adjusting part 3. For specific details, please see the following paragraphs.

Fig. 2 is an enlarged view of a portion of the jaw of the forceps of fig. 1. Fig. 3 is a schematic view of the opened state of the forceps. Fig. 4 is an enlarged view of a portion ii of the forceps of fig. 3. As shown in fig. 2 and 4, in an embodiment, the forceps head 1 includes a first forceps beak 11 and a second forceps beak 12. Further, the distal end of the first beak 11 includes a first half ring groove 11a and a second half ring groove 11 b. The distal end of the second beak 11 includes a first half ring groove 12a and a second half ring groove 12 b. In the utility model, the depth and the width of the half ring groove are about 0.2-0.5mm, so that the strength of the forceps beak is ensured, and the suture line can be clamped to avoid slipping. The distal portions of the binding clip are tapered, i.e., the binding clip has a tapered diameter, and when closed, the first distal portion of the binding clip (i.e., adjacent the first half-ring groove 12 a/the second half-ring groove 12 b) has a diameter of approximately 4-5mm, and the second distal portion of the binding clip (i.e., adjacent the first half-ring groove 11 a/the second half-ring groove 11 b) has a diameter of approximately 2-3 mm.

As shown in fig. 4, the included angle α formed by the center line of the axial portion and the center line of the distal portion of the forceps head is greater than 90 degrees, and in other embodiments, the included angle α may be other angles, such as 120 degrees or 135 degrees, and is not particularly limited.

When the finger ring handle 41 and the finger ring handle 42 are opened, the first and second jaws 11 and 12 of the forceps head 1 are opened as shown in fig. 3. When the first and second beak 11 and 12 are closed, the first half-ring groove 11a and the first half-ring groove 12a form a first full-ring groove, and the second half-ring groove 11b and the second half-ring groove 12b form a second full-ring groove and form a through hole 13. The through hole 13 is positioned between the first full ring groove and the second full ring groove, and the diameter of the through hole 13 is about 0.8mm-1.5 mm.

Fig. 5 is a schematic view of the forceps in a disassembled state. As can be seen from fig. 5, the caliper body 2 includes a connecting tube 21 and a pull rod 22, the pull rod 22 is disposed in the connecting tube 21, and the pull rod 22 is movable in the axial direction. As shown in fig. 6, the proximal ends of the first and second beaks 11 and 12 are connected to the distal end of the forceps body 2 by a pin. Figure 7 sets forth a section view of a portion of forceps VI of figure 5 after installation. As can be seen from fig. 7, the proximal ends of the first beak 11 and the second beak 12 are movably connected to the distal end of the pull rod 22. Fig. 8 is a connection view of the forceps body and the finger ring handle. As shown in FIG. 8, the proximal end of the connection tube 21 is connected to the adjustment part 3, and is fixedly connected to the finger ring handle 41 through the adjustment part 3. The distal end of the pull rod 22 includes a through bore 223 and the distal end of the finger collar shank 42 includes the intermediate connector 32. With further reference to fig. 9, the pull rod 22 is mounted to a finger ring handle 42 by a connector 32, the finger ring handle 42 being connected to a finger ring handle 41 by an intermediate connector 32. As further shown in fig. 3, 7 and 9, when the finger ring handle 41 and the finger ring handle 42 are opened, the finger ring handle 42 pushes the pull rod 22 to move distally, and the opening of the first beak 11 and the second beak 12 is controlled by the pushing of the pull rod 22.

The forceps are operated as follows, and the surgeon ties the suture in a knot, as shown in fig. 10. The first scheme is as follows: in one embodiment, the surgical forceps are opened, the first annular half groove 11a of the first forceps beak 11 is used for clamping the suture line part 61 of the suture line, the first annular half groove 12a of the second forceps beak 12 is used for clamping the suture line part 62 of the suture line, the first forceps beak 11 and the second forceps beak 12 are slowly opened towards two sides, the knot 63 is tightened, and the ligation is completed. The second scheme is as follows: in one embodiment, the surgical forceps are opened, the first and second jaws 11 and 12 are closed, the knot 63 is caught in the through hole 13, the other surgical instrument, such as a forceps, is used to pull, a portion of the pull wire (e.g., 61) on one side is selected, and then the knot 63 is gradually tightened, thereby completing the ligation.

In the embodiment, the functions of the surgical forceps and the instruments of the knot pusher are integrated, so that frequent replacement of surgical instruments is greatly reduced, the surgical operation is convenient, and the tissue injury is reduced and the surgical time is saved.
