During operation, the detachable grasping head can be installed after the rod body is punctured into the abdominal cavity, so that the size of the operation hole (which can reach 3mm or below) can be reduced as much as possible, namely, the size of the operation hole is only dependent on the outer diameter of the rod body and is not dependent on the size of the outer diameter of the grasping head. When the utility model is used for operation, the puncture hole of the rod body is not needed to be sewed, the postoperative pain is slight, and the operation scar can be ignored; and the operation habit is the same as the traditional laparoscopic instrument, so that the medical institution and the doctor who have carried out the traditional laparoscopic operation can use the instrument to carry out the operation without special training, and finally, the operation wound of the patient is further reduced.
Description
Technical Field
The invention relates to the field of medical instruments, in particular to a combined type laparoscope gripper.
Background
The laparoscopic grasper mainly comprises a laparoscopic separation forceps, an intestinal forceps, a grasper, a titanium forceps, a Hem-o-lock clip applier and the like, and the laparoscopic grasper is mainly used for grasping, clamping, separating and clamping vascular tissues and the like in laparoscopic surgery. When the existing laparoscopic instrument is used, a stab card (Troca) with a proper caliber is used as a channel for operating and replacing the corresponding laparoscopic instrument on tissues such as an abdominal wall or a chest wall, and the like, wherein the caliber of the Troca is commonly 5mm, 10mm and 12 mm. Therefore, when using the conventional laparoscopic instruments described above, the incision in the abdominal or thoracic wall must be able to place the corresponding port Troca, and therefore the diameter of the incision must not be less than 5mm, 10mm or 12mm, and suturing is required after the completion of the incision procedure for these ports, which may cause various levels of pain after the operation.
For example, when laparoscopic cholecystectomy is performed clinically, generally, 10mm/12mm and 5mm troca are required to be placed below the umbilical region, the inferior xyphoid and the right costal margin respectively, and the gallbladder is required to be taken out through the inferior xiphoid incision, the original inferior xiphoid incision is required to be enlarged to different degrees under normal circumstances, the original inferior xiphoid incision is mainly prolonged according to the size of the cholecystolithiasis, if the cholecystolithiasis of a patient is large, the inferior xiphoid incision of a part of patients needs to be prolonged to 30mm or even larger, and the anterior abdominorectal sheath at the incision needs to be opened. Clinically, post-operative subcoxial incision pain accounts for the vast majority of complaints.
In order to further reduce the trauma of laparoscopic surgery, single port laparoscopic surgery is performed at the same time. Currently, single port laparoscopic surgery has been widely used, such as transumbilical single port laparoscopic cholecystectomy, appendectomy, salpingectomy, and the like. However, since the observation hole and the operation hole of the conventional single-Port laparoscope are both located at the same Port, an operation triangle cannot be constructed during an operation, so that an angulation design needs to be performed on the original laparoscopic instrument, which brings great difficulty to the design of the single-Port laparoscopic instrument. These situations lead to the following situations: 1. the single-port laparoscope equipment is high in price, and most basic medical institutions cannot be developed; 2. because the traditional operating triangle can not be constructed during the single-port laparoscopic surgery, the special operating triangle constructed by angulation of the instrument puts higher technical requirements on an operator, so that the learning curve of the single-port laparoscopic surgery is obviously prolonged compared with that of the traditional laparoscopic surgery, and the popularization of the technology is hindered; 3. when the single-Port laparoscopic surgery is performed, a large incision is needed to be made on the umbilical region for placing a Port, and the length of the incision is generally obviously larger than that of an observation hole of a common laparoscope.
In response to the above, we have devised a special laparoscopic grasping instrument. The invention mainly has the following characteristics: 1. the instrument has different functional grasping heads with the same size as the grasping heads of the corresponding traditional laparoscope instruments; 2. the outer diameter of the rod body of the laparoscope instrument is obviously smaller (can reach 3mm or below) than the size of the rod body of the existing laparoscope instrument, and the outer diameter of the existing laparoscope instrument is mainly 5mm and 10 mm; 3. the operating handle of the device is not different from the handle of the existing laparoscope device, 4, the device has different functions, the grasping head and the rod body can be conveniently installed and detached, and the operating handle of the device can also be conveniently installed and detached with the rod body.
The use of laparoscopic instruments with the above features for surgery may have the following advantages: on one hand, most laparoscopic surgeries with medium difficulty only need to keep 10mm incisions on the umbilical region, other 2-3 operation holes can be directly punctured by using a rod body with a sharp end and an outer diameter of only 3mm or less, the puncture holes do not need to be sewn after the surgeries, and postoperative pain is slight. On the other hand, as long as corresponding instruments are installed during the operation, the operation habit of the operation is the same as that of the traditional laparoscopic operation, and the result is that: medical institutions and physicians who have performed conventional laparoscopic surgery can perform corresponding operations using the instrument without special training.
