Description

Multifunctional minimally invasive surgery forceps

[ technical field ] A method for producing a semiconductor device

The utility model relates to the technology of medical equipment, especially, relate to a multi-functional minimal access surgery pincers.

[ background of the invention ]

In recent years, laparoscopic surgery, particularly laparoscopic surgery, has developed very rapidly and is currently the most advanced and sophisticated minimally invasive technique. The role in the treatment of surgical disorders has become more and more attractive. Laparoscope is widely applied in the surgical field as a representative of minimally invasive surgery, relates to a plurality of disease types and operations, can be used for simultaneously examining and treating compared with the traditional operation, is well received by patients, especially has small scar after operation and meets the aesthetic requirements, young patients are more acceptable, and the minimally invasive surgery is the general trend and pursuit target of surgical development.

Currently, the golden standard of laparoscopic surgery is cholecystectomy, and most of the general surgical operations, laparoscopic surgery, are generally performed. Such as appendectomy, gastric and duodenal ulcer perforation repair, hernia repair, colectomy, splenectomy, adrenal gland resection, ovarian cyst removal, extrauterine pregnancy, hysterectomy and the like, almost all surgical operations can be performed with the increasing perfection of laparoscopic techniques and the improvement of the operating level of laparoscopic surgeons, and are internationally and prosperously developed. The laparoscopic surgery is to make a plurality of small incisions with the diameter of 5-12 mm at different parts of the abdomen, 2-4 hole operation methods are mostly adopted, one of the small incisions is opened on the navel of a human body, long-strip-shaped scars at the abdominal cavity of a patient are avoided, a camera lens and various special surgical instruments are inserted through the small incisions, images of various visceral organs in the abdominal cavity shot by a camera inserted into the abdominal cavity are transmitted to a television screen, and a surgeon performs the surgery in vitro by using various surgical instruments through observing the images. After recovery, only 1-3 linear scars with the length of 5-12 mm are left on the abdominal cavity, and the abdominal cavity has the advantages of small wound, quick recovery, light pain, high cure rate and the like, so the abdominal cavity is also called as keyhole surgery. The development of the laparoscopic surgery relieves the pain of the patient during the operation, shortens the recovery period of the patient, relatively reduces the expenditure cost of the patient, and improves and innovates surgical instruments with the continuous progress of the science and technology, so that the application space of the laparoscope is larger and larger.

Therefore, the laparoscopic surgery is used as a newly developed minimally invasive method, and as doctors are more and more skillful in operation, many past open surgeries are replaced by intracavitary surgeries, so that the surgery selection opportunities are greatly increased; among them, the forceps are increasingly widely used as an important surgical instrument for laparoscopic surgery. Typically, surgical forceps are used to control fine movements within the patient and to grasp anatomical features. The surgical clamp can comprise a clamping component, a rotating component or/and a cutting component, and the surgical clamp can also comprise electric energy to realize the ion cutting or/and coagulation function in the clamping component. In use, the operator, in order to align the clamping or cutting assembly, needs to rotate the arms to change the angle of the forceps to perform the function of the forceps. Moreover, the operator may further control the gripping assembly, or the rotating assembly, or the cutting assembly while maintaining their arm in a rotated position, such that it is necessary to reposition one or more fingers, and/or the user's hand, and/or the operator's foot to simultaneously perform a collet rotating, gripping, or cutting, or coagulating operation, which, when moved simultaneously or out of coordination with each other, may draw the user's attention to the desired anatomical feature.

The utility model CN201110166911 discloses a common surgical forceps, as shown in fig. 1, the palm is fixed outside the handle 1 ', the middle finger, the ring finger and the little finger are positioned and inside the operating ring 2'; the opening and closing of the tong head are realized through the forward and backward swinging of the operating ring 2'; the adjustment of the circumferential direction of the tong head is realized by pulling the knob 3' by the forefinger. When the operating forceps rod in the abdominal cavity and the forearm of an operator holding the forceps are in a basically parallel direction, the whole palm wraps the handle 1', the operation comfort is good, and the forceps head is not easy to swing and has good stability; however, when the forceps are inserted into the abdominal cavity through the abdominal hole site in the laparoscopic surgery, the range of the angle at which the forceps head can touch the target tissue is not wide enough and flexible. Moreover, when the patient does the laparoscopic surgery, the operator is through the enlarged display screen of the image of endoscope camera system come observe the human intracavity condition and carry out the operation, the display screen is usually fixed, the operator also correspondingly stands in a fixed position and carries out the operation, because the operation time is longer, the operator likes to use the operation pincers of similar utility model CN201110166911 this kind of gun type usually, but because of controlling this kind of pincers in the operation, firstly the angle range that can touch intracavity target tissue is little, secondly operating button or button on handle 1 ' are less or single, if the cutting button 4 ' that control the binding clip head to carry out cutting operation sets up unreasonablely, or lack the button setting of carrying out cutting operation on the handle, and lack the button setting of carrying out the blood coagulation function on handle 1 '.

In order to solve the problem of small angle range of the target tissue in the cavity, the following three methods are generally adopted: (1) one more hole site is opened on the belly of the patient; (2) the operator is temporarily moved to the other side of the patient; (3) and other operating forceps with large angle range for reaching the target tissue in the cavity are used alternately. The method (1) increases the trauma of the patient, and the method (2) increases the fatigue of the operator and the workload of other medical staff; the method (3) not only increases the fatigue of the operator and the workload of other medical staff, but also increases the use cost of the surgical instrument; moreover, all three methods can prolong the operation time and increase the risk of the operation.

Aiming at the problem that the number of operating buttons on the handle is small or single, the cutting button is controlled by the other two hands or the coagulation button is controlled by the foot control button, so that the operator is often required to stop the current action to control other actions in the operation process, the defects that the two hands of the control switch are not coordinated or the hands and the feet are not coordinated and not synchronized easily when the control switch is controlled by the foot are easily caused, the operation is complicated, the attention of the operation operator is dispersed, the operation time is prolonged, and the operation risk is increased; in addition, the scattered arrangement of the operating buttons on the handle also easily causes the insecure gripping of the handle by an operator, and the operator cannot effectively, simply and conveniently open and peel off tissues, thereby increasing the risk of the operation.
