Description

Technical Field

[0001] The utility model relates to the field of bipolar electrocoagulation dissectors based on hemostatic forceps. Background Art

[0002] Minimally invasive surgery is a very important development link in today's medical technology. It only causes minimal trauma to patients during the operation and only leaves a small wound after the operation. Compared with traditional surgery, it has the characteristics of small incision, small trauma, fast recovery, and less pain. These characteristics are the medical revolution brought by minimally invasive surgery. Taking laparoscopic minimally invasive surgery as an example, during the operation, a variety of long-handled surgical instruments will be used to assist the operator to complete actions such as cutting, poking, and clamping in a narrow space. During the operation, in order to prevent the target organ from increasing the difficulty of the operation due to excessive bleeding or blood vessel rupture, the blood vessels or nearby tissues connecting the target organ will first be ligated and hemostatic with a medical clamp, and the instrument used is a hemostatic forceps. The action mode of the hemostatic forceps is to first insert the hemostatic forceps into the human body and apply force from the outside to drive the clamp to clamp the blood vessel or tissue to achieve the hemostatic effect.

[0003] However, the existing hemostatic forceps are not actually well combined with long-handled surgical instruments, and have the defects of inconvenient operation and increasing the operation difficulty of the operator. Content of the Utility Model

[0004] In view of the above problems, the utility model provides an aspirating bipolar electrocoagulation dissector, which can not only well combine the bipolar electrocoagulation based on the hemostatic forceps with the long-handled surgical instrument, but also enable the operator to operate with one hand, and improve the effective execution of technical actions during the operation through the simplicity and stability in the operation.

[0005] The technical solution of the utility model is as follows: it includes a hollow rod body 1, an operation handle 2 fixedly connected to the rear end of the hollow rod body 1, and a clamp 3 telescopically installed at the front end of the hollow rod body 1;

[0006] The clamp 3 includes a clamp seat 31, a slider 32, and a pair of clamp fingers 33. The clamp seat 31 is fixedly installed at the end of the hollow rod body 1; the middle parts of the pair of clamp fingers 33 are hinged through a rotating shaft, and the rotating shaft 320 is also fixedly installed on the slider 32. A pair of chutes 310 are opened at the rear of the clamp seat 31. The chutes 310 are arc-shaped that converge towards the center of the clamp seat 31 from back to front. The rear parts of the pair of clamp fingers 33 are fixedly connected with guide rods 330 extending into the chutes 310;

[0007] A slider driving mechanism 5 for driving the slider 32 to reciprocate is also provided in the hollow rod body 1. The pair of clamp fingers 33 are insulated from each other, and are respectively connected to a positive electrode wire 34 and a negative electrode wire 35.

[0008] Furthermore, the slider driving mechanism 5 includes a second push rod 51, a second connecting rod 52 and a second pushing block 53. The second push rod 51 passes through the hollow rod body 1 and the operating handle 2, and its front end is fixedly connected to the slider 32. A second groove and a second long hole parallel to the axial direction of the operating handle 2 are formed on the surface of the operating handle 2. The second pushing block 53 is slidably received in the second groove, and the second connecting rod 52 is slidably received in the second long hole. Both ends of the second connecting rod 52 are fixedly connected to the second push rod 51 and the second pushing block 53 respectively.

[0009] Furthermore, an aspiration tube mechanism 4 is further provided inside the hollow rod body 1, which includes an aspiration tube 41, a first connecting rod 42 and a first pushing block 43. The aspiration tube 41 sequentially passes through the clamp seat 31, the hollow rod body 1 and the operating handle 2. A first groove and a first long hole parallel to the axial direction of the operating handle 2 are formed on the surface of the operating handle 2. The first pushing block 43 is slidably received in the first groove, and the aspiration tube 41 and the first pushing block 43 are fixedly connected by the first connecting rod 42. The first connecting rod 42 is slidably received in the first long hole.

[0010] In the present utility model, the reciprocating movement of the clamp seat driven by the seat body driving mechanism enables the position adjustment of the catheter and the clamping or releasing action of the clamping fingers to be independently completed by two pushing blocks on the operating handle after the hollow rod body extends in place, which is very convenient to operate. The present utility model combines a hemostatic forceps and a long-handled surgical instrument well as a whole, and has simple operation and wide application range. It can be used in various endoscopic surgeries, including endoscopic long-handled applications (laparoscopy, thoracoscopy), and also includes short-handled surgical instruments under endoscopy, such as arthroscopes, hysteroscopes, nasal endoscopes and micro-otoscopic instruments.

[0023] To clearly illustrate the technical features of this patent, the following will elaborate on this patent in detail through specific embodiments and in conjunction with its accompanying drawings.

[0024] This case, as Figures 1 - 3 shown, generally includes a hollow rod body 1, an operating handle 2 fixedly connected to the rear end of the hollow rod body 1, and a clamp 3 telescopically installed at the front end of the hollow rod body 1;

[0025] The clamp 3 includes a clamp seat 31, a slider 32, and a pair of clamping fingers 33. The clamp seat 31 is fixedly installed at the end of the hollow rod body 1; the middle parts of the pair of clamping fingers 33 are hinged through a rotating shaft, and this rotating shaft 320 is also fixedly installed on the slider 32. A pair of sliding grooves 310 are formed at the rear of the clamp seat 31. The sliding grooves 310 are arc-shaped and converge towards the center of the clamp seat 31 from the rear to the front. The rear parts of the pair of clamping fingers 33 are fixedly connected with guide rods 330 extending into the sliding grooves 310;

[0026] A slider driving mechanism 5 for driving the slider 32 to reciprocate is further provided in the hollow rod body 1. Insulation is maintained between the pair of clamping fingers 33, and they are respectively connected to a positive electrode wire 34 and a negative electrode wire 35. (The wires in the figure are not drawn completely)

[0027] In this way, on the one hand, the movement of the clamp seat 31 driven by the hollow rod body 1 enables it to extend into the specified position driven by the hollow rod body 1. Thereafter, since the rotating shaft 320 is in the front and the guide rod 330 is in the rear, when the slider driving mechanism 5 drives the slider 32 to make a reciprocating motion relative to the clamp seat 31, a pair of clamp fingers 33 can be driven to approach or separate from each other, realizing the basic actions of the hemostatic forceps. After the positive electrode wire and the negative electrode wire connected to the two clamp fingers are connected to the positive and negative electrodes of the power supply, the basic structure of bipolar electrocoagulation can be formed.

[0028] The slider driving mechanism 5 includes a second push rod 51, a second connecting rod 52, and a second pushing block 53. The second push rod 51 passes through the hollow rod body 1 and the operating handle 2, and its front end is fixedly connected to the slider 32. A second groove and a second long hole parallel to its axis are formed on the surface of the operating handle 2. The second pushing block 53 is slidably accommodated in the second groove, and the second connecting rod 52 is slidably accommodated in the second long hole, and both ends of the second connecting rod 52 are fixedly connected to the second push rod 51 and the second pushing block 53. In this way, the operator holds the operating handle, presses the first pushing block with one finger, and then pushes the second pushing block with another finger, so as to control the opening or closing of a pair of clamp fingers, and the clamping ability of the overall structure can be maintained by keeping the thrust after clamping.

[0029] An aspiration tube mechanism 4 is further provided inside the hollow rod body 1, which includes an aspiration tube 41, a first connecting rod 42, and a first pushing block 43. The aspiration tube 41 sequentially passes through the clamp seat 31, the hollow rod body 1, and the operating handle 2. A first groove and a first long hole parallel to its axis are formed on the surface of the operating handle 2. The first pushing block 43 is slidably accommodated in the first groove, and the aspiration tube 41 and the first pushing block 43 are fixedly connected by the first connecting rod 42, and the first connecting rod 42 is slidably accommodated in the first long hole. In this way, the operator holds the operating handle and pushes the first pushing block with the thumb to adjust the extension amount of the aspiration tube 41.

[0030] There are many specific implementation ways of the present invention. The above description is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements can be made, and these improvements should also be regarded as the protection scope of the present invention.
