Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to fine setting laparoscopic surgery sword.
Background
Endoscopic surgery is a surgery performed using an endoscope and its associated instruments. The cold light source is used for providing illumination, the cavity mirror lens (the diameter is 3-10mm) is inserted into a body cavity, the digital camera shooting technology is used for leading the image shot by the cavity mirror lens to be transmitted to a post-stage signal processing system through an optical fiber, and the image is displayed on a special monitor in real time. Then the operator analyzes and judges the state of an illness of the patient through images of different angles of the organs of the patient displayed on the monitor screen, and performs the operation by using special endoscope instruments. The laparoscopic surgery mostly adopts a 2-4 hole operation method, taking the laparoscopic surgery as an example, wherein one hole is opened on the navel of a human body, so that a long-strip-shaped scar is avoided being left at the abdominal cavity part of a patient, and after recovery, only 1-3 linear scars of 0.5-1 cm are left at the abdominal cavity part.
The following problems exist in the process of traditional endoscopic surgery: 1. when the endoscopic surgery is carried out, the length of the scalpel is fixed and cannot be adjusted as required; 2. the body cavity image is not clear due to insufficient light and too large body cavity depth, so that the operation time is prolonged, and the operation progress is influenced; 3. aiming at organ operations (such as thyroid, mammary gland and gall bladder) at different parts, the length requirements of the endoscopic electric scalpels are different, but the whole length of the current endoscopic electric scalpels is fixed, an operator needs to manually adjust the length and the angle to the optimal length and angle, the operation is time-consuming and labor-consuming, and the operation is very inconvenient.
Therefore, patent CN206228419U discloses a novel endoscope electric scalpel with adjustable length, which has the advantages that: the length that the knife rest stretches out is adjusted through knife rest adjusting button, and the position and the angle of reasonable control scalpel make the operator more convenient, effectual perform the operation, have improved operation efficiency, have simplified the operation of operation, have shortened the operation time. Although it can adjust the length of the knife rest, it still has the problems that the adjusting length is difficult to control accurately and fine-tune accurately because the operation needs extremely accurate control.

Optionally, a cold light lamp and a camera are arranged on the side wall of the boss.
Optionally, a power indicator and a power switch are arranged on the outer side wall of the knife handle.
Optionally, the tail end of the knife handle is connected with a display device.
Optionally, the display device includes a display, and the display is connected to the camera through a data line.
Optionally, the tool holder and the tool shank are both cylindrical.
The during operation, give whole equipment power supply through the power cord, power indicator can light after the switch on, then slowly insert the handle of a knife in the sword hole of opening in advance, after the part of taking the camera of handle of a knife front end enters into the coelom, the camera can show image information on the display through data transmission line with the coelom image information of gathering, after the condition is observed clearly to the coelom, make the handle of a knife front end promote forward through rotating the knob cover, carry out the accurate fine setting of electrotome position, open switch after confirming the position again, can start the electrotome and carry out the operation.
The utility model has the advantages that: the utility model discloses in, through design fine-tuning pole, the thread bush, the knob cover of cooperation fine-tuning pole and slide the guide arm and slide the guide block, realize the accurate fine setting to the electrotome position, solved the problem that traditional electrotome stretches out length can not accurate fine setting, improved the efficiency of operation and reduced the risk of operation.
