Abstract

A separating forceps equipped with a suction device for minimally invasive surgery comprises a handle (5), a forceps head (1), and a forceps rod (3) disposed between the handle (5) and the forceps head (1). There are provided at the junction of the handle (5) and the forceps rod (3) a connector (6) for an external power supply, a tube joint (8) for connecting to the suction device, and a contact switch (4) for the suction device. The suction device is in electric connection with the contact switch (4), and is controlled by the contact switch (4). The forceps head (1) is of a rounded and blunt shape. There are suction holes (2) provided at the opening/closing part of the forceps head (1), grooves (10) provided on the inner sides thereof, and serration projections (11) provided on the edges thereof. The forceps head (1) having a rounded and blunt shape, would cause limited damage to tissue when used for separating tissues, and can grip tissue. The forceps head (1) equipped with the suction device has a suction function, so that it is not necessary to change instruments frequently during a minimally invasive surgical operation, thus shortening the time of the operation and increasing the safety of the operation. The curvature of the forceps rod (3) is adjustable, so as to facilitate its manipulation during a surgical operation.

Description

Separating forceps with suction device for surgical minimally invasive surgery

Technical field

The utility model relates to a medical device, in particular to a multi-purpose separating pliers with a suction device for surgical minimally invasive surgery. Background technique

In surgical minimally invasive surgery, the separation forceps, the aspirator, are the most commonly used minimally invasive surgical instruments. For example, laparoscopic surgery usually requires three or one passage in the abdomen for surgery. When a doctor performs an operation, it is often necessary to replace a different surgical instrument for the separation during surgery, the clamping of the forceps, the attraction of the suction device, and the like. Because the minimally invasive surgical instruments are relatively long, frequent replacement not only increases the operation time, but also increases the possibility of surgical misoperation. Laparoscopic surgery

98% is operated by the surgeon alone. From the time of encountering large bleeding, the surgeon often has difficulty in operating both hands. Changing the device alone can increase the risk of surgery. Summary of the invention

The technical problem to be solved by the present invention is to provide a separation forceps with a suction device for surgical minimally invasive surgery, which can realize blunt separation during surgery, holding tissue, attracting water, blood, smoke and hemostasis. Function, easy to operate, avoid frequent replacement of surgical instruments, greatly shorten the operation time; Provide adjustable caliper curvature and knob to facilitate better vision in minimally invasive surgery and prevent devices from interacting with each other during operation.

In order to achieve the above object, the technical solution adopted is: a separating pliers with a suction device for surgical minimally invasive surgery, including a handle, a pliers head, and a pliers with an inner channel that is placed between the handle and the pliers and connected to each other. a rod, characterized in that: the handle and the tong rod connecting portion are provided with an external power connector, a pipe interface connected to the suction device, and a suction device contact switch, the suction device is electrically connected to the contact switch, and is subjected to the contact Point switch control; the clamp head is round and blunt-shaped, the clamp head has a suction hole at the opening and closing, the inner side is provided with a groove, and the edge has a serrated protrusion.

The middle of the tongs is provided with a camber adjustment, and the handle is provided with a caliper camber adjustment knob, and the caliper camber is controlled by the caliper camber adjustment knob.

The caliper rod has a suction duct built therein, and the front end of the nipper is opened and closed, and then communicates with the tube interface of the handle joint portion. The beneficial effects of the present invention are: designing a multi-purpose minimally invasive surgical separation forceps. The head of the pliers is blunt and round.

Confirmation Separation is small and safe for tissue damage. It can be used to hold tissues and stop bleeding. The head of the pliers with suction device is designed to attract water, blood and smoke. Multi-purpose multi-purpose design, no need to replace a variety of instruments, can be completed by one hand, can shorten the operation time, easy to operate. In the case of major bleeding, the superiority of the invention can be better displayed, and the patient can be restrained while holding blood, thereby increasing the safety of the operation and reducing the risk of surgery. The curvature of the caliper can also be adjusted during single-port laparoscopy, which is more conducive to intraoperative operation. DRAWINGS

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

Figure 1 is a schematic view of the structure of the present invention;

Fig. 2 is a schematic view showing the structure of the present invention when a single-hole laparoscope is applied.

In the figure: 1 clamp head; 2 - suction hole; 3 - clamp rod containing suction pipe; 4 one contact switch; 5 - handle; 6 - external power connector; 7 - camber adjustment knob; Pipe interface; 9-clamping camber adjustment; 10-clamp head groove; 11-saw-toothed projection. detailed description

A schematic view of the structure of the present invention is shown in FIG. 1. As can be seen from the figure, a separating pliers with a suction device for surgical minimally invasive surgery includes a handle 5, a clamp head 1, and is placed between the handle 5 and the clamp head 1 and connected to each other. The tong rod 3 of the inner channel is characterized in that: the connecting portion of the handle 5 and the tong rod 3 is provided with an external power connector 6, a pipe interface 5 connected to the suction device, and a suction device contact switch 4, the suction device and the suction device The contact switch 4 is electrically connected and controlled by the contact switch 4; the clamp head 1 has a round blunt shape, the clamp head 1 is open and closed with a suction hole 2, and the inner side is provided with a groove 10, and the edge has A serrated protrusion 11.

The caliper rod 3 has a suction duct built therein, and the front jaw 1 is opened and closed, and then communicates with the tube joint 8 of the handle joint portion.

The middle of the tongs 3 is provided with a curvature adjustment 9. The handle 5 is provided with a caliper curvature adjustment knob 7, and the caliper 3 is controlled by the caliper curvature adjustment knob 7.

As shown in the figure, the jaw 1 is round and blunt, and the tissue can be bluntly separated. The edge of the clamp head 1 has a serrated protrusion 11 for holding the tissue, and the tube interface 8 of the suction device is connected to the vacuum suction device. When the clamp head 1 is opened, the suction device can also be opened by the contact switch 4 on the handle. The smoke and the liquid are sucked, and the liquid is sucked through the suction hole 2 of the jaw when the jaw is closed. Through the handle power connector 6, it can be connected to unipolar coagulation, and when the small blood vessels are added, the electrocoagulation will stop bleeding.

By the present invention, it is not necessary to frequently change instruments, and one-hand operation can perform various functions such as tissue separation, tissue holding, and absorption of liquid and gas.

In the case of single-hole laparoscopy, the camber of the adjustment clamp 3 can also be controlled by the clamp curvature adjustment knob 7, which is more conducive to the operation.

The above description of the specific embodiments is intended to describe and explain the technical aspects of the invention. It is to enable those skilled in the art to practice the invention. However, it is to be understood that the invention is not limited to the embodiments discussed above, and any obvious alterations or substitutions based on the teachings of the invention are also considered to be within the scope of the invention.
