Detailed Description
All of the features disclosed in this specification, or all of the steps in a method or process disclosed, may be combined in any combination, except for mutually exclusive features and/or steps.
Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. That is, each feature is one example only of a generic series of equivalent or similar features, unless expressly stated otherwise.
As shown in fig. 1, which is a schematic overall structure of the present embodiment, the entire laparoscopic surgical instrument includes three parts, a front part a, a rear part B and a hand-held end C, which can be separated and connected to each other, thereby realizing a detachable assembled structure.
As shown in fig. 2 and 3, the front section a is schematically shown, wherein the forceps head A1 has a connecting end, one end of which is fixedly connected with the forceps, and the other end of which is used for connecting the first protective casing A2 and the first traction strip A3. The first traction strip A3 is fixedly connected with the surgical forceps into a whole, and the switch closing of the surgical forceps is realized by pulling the first traction strip A3. The outer surface of the end part of the first protective barrel A2 is provided with a groove A4, and a protruding structure is arranged in the clamp head A1 at the corresponding connection part, when connection is carried out, the first protective barrel A2 is sleeved on the first traction strip A3, and then the first protective barrel A2 is inserted into the clamp head A1 through the mutual matching of the groove and the protruding structure. Because the internal diameter of binding clip A1 junction is greater than the external diameter of first protective casing A2, and both adopt the surface interference contact's mode to laminate outside the back of carrying out the lock connection, consequently binding clip A1, first protective casing A2, first traction strip A3 three can form an overall structure, drives the other two co-movements when first traction strip A3 rotates or removes.
As shown in fig. 4, the rear section B includes a second casing B1 and a second traction bar B3, wherein the second casing B1 has a larger diameter than the first casing A2, and one end of the first casing A2 is inserted into the second casing B1, and the two casings are connected by threads. The diameter of the second traction bar B3 is larger than that of the first traction bar A3, a wedge opening is formed in the end portion of the second traction bar B3, the first traction bar A3 can be inserted into the wedge opening, then external threads are formed in the surface of the second traction bar B3, a locking sleeve B2 is connected, the first traction bar A3 is extruded through the wedge opening is folded through rotating the locking sleeve B2, and therefore the first traction bar A3 and the second traction bar B3 are fixedly connected, and the locking sleeve is shown in fig. 5.
In the actual operation process, after a laparoscopic surgery channel is established through the existing surgery flow, the forceps head A1 and the first traction strip A3 in the anterior segment A in the embodiment are sent into the abdominal cavity of a patient together through the laparoscopic surgery channel, the first protection barrel A2 is penetrated into the abdominal cavity from the external part of the abdominal cavity of the patient in a penetrating mode, then the first traction strip A3 is led out of the abdominal cavity from the first protection barrel A2, and meanwhile the first protection barrel A2 is in butt joint with the forceps head A1, so that the integral assembly of the anterior segment A is completed. Then carry out locking connection with second traction bar B3 and first traction bar A3, then behind the cover of second pile casing B1 on second traction bar B3, carry out threaded connection with first pile casing A2 again, with second pile casing B1 and the syntropy end of second traction bar B3 through the mode of buckle with hold end C and be connected, the surgical instrument after accomplishing is as shown in FIG. 1. The assembled surgical instrument can perform surgical operation on a patient, and a laparoscopic surgical channel is not occupied in the surgical operation process, and because the diameters of the first protective cylinder A2 and the first traction strip A3 are very small, the puncture can not leave a larger scar on the abdomen of the patient. When the procedure is completed, the above steps are reversed and the anterior segment portion a is then removed from the patient's abdominal cavity.
In this embodiment, the binding clip is only one representation of all laparoscopic surgical instruments: the forceps head can be scissors, an electrocoagulation hook, bipolar electrocoagulation and other traditional laparoscopic surgical instruments, and can be assembled by adopting the method.
The utility model is not limited to the specific embodiments described above. The utility model extends to any novel one, or any novel combination, of the features disclosed in this specification, as well as to any novel one, or any novel combination, of the steps of the method or process disclosed.
