Description

Laparoscopic surgery operation forceps with forceps mouth capable of being repeatedly separated from multiple connection
Technical Field
The invention relates to the technical field of surgical laparoscopic surgery, in particular to a pair of laparoscopic surgery operating forceps with forceps mouths capable of being repeatedly separated from multiple joints.
Background
Surgical treatment has entered a minimally invasive age, and laparoscopic surgery has become widespread in various medical institutions around the world as a representative of minimally invasive treatment. The blood vessel treatment is a difficult problem often faced by the laparoscopic surgery, unlike the traditional development surgery, the hemostatic operation of damaged blood vessels under the laparoscope can only be completed by a long laparoscope operating clamp, and the laparoscopic treatment has no doubt to face more and more difficult difficulties than the traditional development surgery in the hemostatic and blood vessel repairing operation which lasts for a plurality of seconds, and the main focuses are expressed as the following points:
firstly, the operating space under the laparoscope is small, and because the endoscope has a visual field amplifying effect, the whole visible range of the operation area is limited, so that a little bleeding can obviously influence the operation visual field, and the unclear visual field of the operation area can block the hemostasis operation, thereby causing vicious circle and increasing the operation difficulty;
second, laparoscopic surgery is performed through 3-5 trans-abdominal access ports, which only allow access to a single forceps. When the blood vessel is ruptured and bleeds, the operating forceps (or the suction apparatus) with different functions need to be continuously replaced, and the operating forceps (or the suction apparatus) repeatedly enters and exits the abdominal wall channel, so that the repeated replacement action usually delays time, and great inconvenience is brought to an operator in the process of the hemostasis operation which strives for seconds;
thirdly, laparoscopically aiming at bleeding from a ruptured blood vessel, the common practice at present is to use a head-lock disposable clip to clamp the blood vessel, the clip only irreversibly clamps the blood vessel, when important blood vessel bleeding is involved, the use of the clip completely seals the blood vessel and abandons the opportunity of repairing the blood vessel, which means that in an emergency situation, the blood vessel can only be sacrificed to ensure the stability of the vital signs of a patient. However, clamping and closing important blood vessels often causes failure of important organs after surgery, and causes complications.
Disclosure of Invention
In order to solve the defects of the prior art, the laparoscopic surgery operation forceps with the forceps mouth capable of being repeatedly disconnected and reconnected are provided, and the hemostatic forceps can rapidly and quickly stop bleeding but can not permanently clamp and close blood vessels.
The laparoscopic surgery operation forceps with the forceps mouth capable of being repeatedly disconnected from multiple joints comprise the forceps mouth, a barrel and a handle, wherein an inner sleeve is arranged in the barrel, the forceps mouth is hinged to the front end of the barrel, two sides of the forceps mouth are hinged to the front end of the inner sleeve through an opening and closing linkage rod, a linkage mechanism is arranged in the handle and connected with an operation rod, a limited clamping mechanism is arranged in the operation rod, a clamping block is arranged in the inner sleeve corresponding to the limited clamping mechanism, a locking mechanism is arranged at the top end in the inner sleeve, and the locking mechanism is matched with the operation rod to fix the position of the inner sleeve in the barrel.
As a further improvement of the scheme, the linkage mechanism comprises a linkage metal rod, a rotating shaft and a handle, the handle is sleeved on the rotating shaft, the front end of the linkage metal rod is connected with the operating rod, and the rear end of the linkage metal rod is connected with the handle.
As a further improvement of the scheme, the front end of the linkage metal rod is provided with a handle connecting screw, and the rear end of the operating rod is provided with an operating rod connecting screw corresponding to the handle connecting screw.
As a further improvement of the above scheme, the position limiting mechanism comprises a lever rotating shaft and an X-shaped metal lever, the lever rotating shaft and the X-shaped metal lever are arranged inside the operating rod, the X-shaped metal lever is sleeved on the lever rotating shaft, a pair of buckle and retraction button are respectively arranged at the front end and the rear end of the X-shaped metal lever, a through groove is arranged on the operating rod corresponding to the buckle and the retraction button, and the buckle and the clamping block are correspondingly arranged.
As a further improvement of the above scheme, a return spring is arranged between the pair of buckles.
As a further improvement of the above scheme, the locking mechanism includes a U-shaped member and a central pivot shaft which are arranged in an inner sleeve, the outer end of the U-shaped member is connected with a traction rope, the traction rope is wound out from the central pivot shaft, a cross clamping rod is arranged at the end of the traction rope, a clamping groove is formed in the side wall of the inner sleeve corresponding to the cross clamping rod, the inner side of the cross clamping rod is connected with the outer wall of the inner sleeve through a compression spring, and a strip-shaped clamping groove is formed in the inner side of the cylinder corresponding to the cross clamping rod.
The invention has the beneficial effects that:
compared with the prior art, the laparoscopic surgery operation forceps provided by the invention have the advantages that the forceps mouth can be repeatedly separated from multiple connection:
1. the ordinary operation field exposure operation and the hemostasis operation in the laparoscopic surgery are combined into a whole, and the operation can be quickly finished by the same operating forceps. When the bleeding caused by rupture of the blood vessel is found in the operation, the bleeding part is clamped by using the operating forceps, then the button at the tail end of the operating rod is pressed, the forceps nozzle is separated from the operating rod, and the forceps nozzle remained at the bleeding part becomes a temporary hemostatic clip. After the bleeding damage is cleaned and anastomosed, the forceps mouth and the operating rod are reconnected, and finally the forceps mouth is loosened, so that the hemostasis operation is completed, and meanwhile, the operation forceps can be continuously used for performing the operation in the operation. The design avoids the trouble of repeatedly replacing operating instruments and even increasing abdominal wall channels, and is particularly favorable for hemostasis anastomosis which strives for seconds;
2. the forceps mouth of the operation forceps can be connected in a multiple mode after separation, so that the closed state of a clamped blood vessel can be released after hemostasis is finished, the blood circulation function of the operation forceps is recovered, permanent blood vessel clamping caused by the use of a disposable head-lock clamp is avoided, and in addition, the cost of using a disposable consumable clamp is also saved as the operation forceps mouth can be recycled;
3. the operation forceps are simple to use, simplify the hemostasis operation process, reduce the learning difficulty of a beginner laparoscopic operator, and are beneficial to quickly improving the technical operation level of the laparoscopic operation of the operator.
