Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to an endoscopic forceps convenient to suture.
Background
The laparoscopic surgery is a newly developed minimally invasive surgery and is a necessary trend for the development of future surgical methods. With the rapid advance of industrial manufacturing technology, the fusion of related disciplines lays a firm foundation for the development of new technology and new method, and the more and more skillful operation of doctors makes many of the past open operations replaced by the intracavitary operations, thereby greatly increasing the operation selection opportunities.
When laparoscopic prostate cancer radical surgery is performed, the pubic prostate ligament needs to be sutured. Because the pubic prostatic ligament is internally provided with a plurality of blood vessel nets formed by blood vessels, if the pubic prostatic ligament is not sutured or sutured in place, the blood vessels are easy to bleed, but because the pubic prostatic ligament tissue is thicker, the width can be about one centimeter, and the blood vessels are rich and have small space, the suturing is difficult, and the blood vessels are easy to bleed in the suturing process. The traditional sewing method is as follows: doctors draw the prostate to directly suture after exposing the pubic prostate ligament, but because the suture space is small and only a small suture needle (the length of the needle is about 1 cm) can be placed, the length of the needle is close to the thickness of the pubic prostate ligament, and the needle head is not easy to expose; in addition, the suture needle is arc-shaped, the tissue is too thick, and the needle outlet point is not easy to be accurately controlled, so that the suture is difficult. Because the ligament is not fixed in the sewing process, the ligament can be dislocated when a doctor punctures the ligament by using a sewing needle, the sewing is not in place, and the sewing difficulty is increased.
SUMMERY OF THE UTILITY MODEL
Aiming at the technical problem that ligaments cannot be effectively fixed under the traditional laparoscopic surgery, the utility model provides an endoscopic forceps convenient to suture.
The technical scheme adopted by the utility model is as follows: the endoscopic forceps convenient to suture comprise a forceps handle, a forceps rod and two forceps heads, wherein a handle is arranged on the forceps handle, the forceps heads are made of metal, two notches convenient for a suture needle to penetrate are formed in the forceps heads, each notch is in a V shape, the bottom of each notch is wide, and the top of each notch is narrow. Although the pubic prostate ligament is about one centimeter wide, the pubic prostate ligament is a soft tissue that is soft and can be compressed. When in suturing, a doctor uses the forceps of the endoscopic forceps to press the thin ligament, and the ligament to be sutured is flattened or clamped; when the ligament tissue is pressed to be thin, the endoscopic forceps are reserved, a doctor uses the suture needle to penetrate through the bottom of the notch back and forth to suture the ligament, and after the suture is sewn, the suture can be taken out from the top of the notch, so that the endoscopic forceps are prevented from being sewn on the tissue. Compared with the traditional single suture mode, the endoscopic forceps suture the tissue by means of the notches on the endoscopic forceps, the endoscopic forceps can effectively fix the tissue during suture, and the problems that the tissue is dislocated and the direction of a needle head is not easy to control in the suture process are solved, so that the suture difficulty is greatly reduced, and the suture time is shortened.
Furthermore, the inner sides of the two forceps heads are toothed, so that the friction force between the forceps heads and tissues is increased, the forceps heads can better clamp the tissues, and the tissues are prevented from sliding.
Furthermore, an electrode joint electrically connected with the forceps head is arranged on the forceps handle, so that the endoscopic forceps have an electrocoagulation function, after the electrode joint is electrified, the forceps head heats tissues when contacting with the body through high-frequency high-voltage current generated by the tip of the effective electrode, and the coagulation of the body tissues is realized, thereby achieving the purpose of hemostasis.
Further, the forceps heads are coated with insulating coatings, and electrocoagulation parts are arranged at positions, close to the end parts, of the inner sides of the two forceps heads. That is, the electrocoagulation portion is bare metal, the electrocoagulation portion is not coated with an insulating coating, and the rest parts of the forceps head except the electrocoagulation portion are coated with the insulating coating. The purpose of this is to: because the exposed metal area of the forceps head is too large, side damage is easy to occur to electrocoagulation, and because the contact area is too large, even the electrocoagulation function cannot be excited. Therefore, under the condition of ensuring the length of the traditional laparoscope forceps head, the utility model coats most of the insulating coating on the forceps head, and does not coat a small part of the forceps head. The forceps head coated with the insulating coating does not have the electrocoagulation function, and the electrocoagulation part not coated with the insulating coating has the electrocoagulation function, so that the electrocoagulation range is narrowed, and medical staff can achieve accurate electrocoagulation.
Furthermore, the insulating coating is one of an alumina ceramic coating or a ceramic polymer coating, and the two coatings have mature technologies and can realize an insulating function.
Furthermore, the electrode joint comprises a positive electrode joint and a negative electrode joint arranged beside the positive electrode joint, the positive electrode joint is electrically connected with one binding clip, and the negative electrode joint is electrically connected with the other binding clip. The electrocoagulation mode is monopolar electrocoagulation, wherein during operation, the electrode joint is connected with a positive electrode or a negative electrode, and then a corresponding negative electrode or a positive electrode patch is adhered to the skin surface of a patient. After the electric coagulation function of the forceps head is excited, the positive electrode and the negative electrode are communicated, and weak current can pass through the patient. For a common patient, a weak current in the body cannot cause damage, but for the patient with a metal foreign body (such as a pacemaker, an orthopedic metal steel plate, a steel nail and the like) in the body, the metal foreign body can conduct electricity and be excited, so that the performance of the metal foreign body is influenced, and the body of the patient is damaged. Therefore, the technical scheme adopts a bipolar type, when two forceps heads contact tissues needing electrocoagulation, the electrocoagulation function is activated, blood vessels at the position of a suture needle channel can be coagulated, bleeding caused by puncture of a suture needle is reduced, a current forms a loop through a positive electrode connector, the forceps heads, the tissues and a negative electrode connector, and the current burns and coagulates the tissues between the two forceps heads through the tissues between the two forceps heads. That is to say, the electric coagulation process can not have the electric current and pass through from the internal long distance of patient to can satisfy the patient that installs the metallic foreign matter in the health and use, improve chamber mirror pincers's commonality and accurate nature. After the bipolar coagulation is utilized, the operation visual field is clear in the suturing process, and the visual field cannot be polluted by bleeding to cause the visual field to be unclear.
The utility model has the beneficial effects that:
1. the utility model sews by means of the gap on the endoscopic forceps, the endoscopic forceps can effectively fix the tissue during sewing, and the dislocation of the tissue during sewing is avoided, thereby greatly reducing the sewing difficulty and shortening the sewing time.
2. The endoscopic forceps not only can play a role in assisting in suturing, but also has an electrocoagulation function, and the forceps head heats tissues when contacting with the body through high-frequency high-voltage current generated by the tip of the effective electrode, so that the coagulation of the body tissues is realized, and the purpose of stopping bleeding is achieved.
3. The endoscope forceps adopt bipolar electrocoagulation, when two forceps heads contact tissues needing electrocoagulation, the electrocoagulation function is activated, and current forms a loop through a positive electrode joint, the forceps heads, the tissues and a negative electrode joint. That is to say, the electric coagulation process can not have the electric current and pass through from the internal long distance of patient to can satisfy the patient that installs the metallic foreign matter in the health and use, improve chamber mirror pincers's commonality and accurate nature.
4. After the endoscopic forceps utilize bipolar electrocoagulation, the surgical field of vision is clear in the suturing process, and the visual field is not clear due to hemorrhage pollution.
