Description

Dual-purpose medical hemostatic forceps with locking function

Technical Field

The utility model relates to a hemostatic forceps, in particular to a dual-purpose medical hemostatic forceps with a locking function, belonging to the technical field of medical appliances.

Background

The hemostatic forceps are common instruments in surgical operations and used for clamping blood vessels to achieve blood blocking, however, the existing hemostatic forceps still have the defect that two points are obvious, on one hand, the locking effect is poor, on the other hand, the forceps head does not have a replacing function, or the forceps head has the replacing function but has the defect that the replacing structure has defects, and the actual application effect is poor.

The application number is CN201621183527.3, the publication number is CN207012219U, and the name is a Chinese utility model granted patent of a hemostatic forceps, the locking form of the Chinese utility model is basically consistent with that of the conventional hemostatic forceps, and the Chinese utility model granted patent has the function of replacing the forceps head. It is specific, its inboard stationary blade that has the latch that sets up mutual interlock of two pincers handles and then realize the locking effect, and the defect that its exists is only just can lock hemostatic forceps in latch interlock position, and part is invalid between the adjacent latch, leads to the position of hemostatic forceps locking to receive the restriction, and the locking effect that hardly guarantees latch interlock position is just in time, very easily appears the problem of tension or too loose. In addition, it sets up the loading and unloading change that the threaded rod realized the hemostasis (holding) chuck in hemostatic forceps head one end, and the drawback that exists is also more obvious, and it is long-time to screw up the change and leads to threaded connection relief angle to have the deviation easily, and two clamping surfaces probably no longer are relative forward after changing the head and screwing up, lose stable centre gripping effect promptly.

The application number is CN 20202172722323.9, the publication number is CN213249431U, the name is the special hemostatic forceps's of department of general surgery's china utility model granted patent, it does not possess binding clip and changes the function, improved the locking form, can control hemostatic forceps to open and the closed operation through setting up pushing mechanism, set up stop gear through one side at pushing mechanism simultaneously, can carry on spacingly to hemostatic forceps after the closure, thereby make medical personnel need not to hold hemostatic forceps always when carrying out hemostatic operation, and then can reduce medical personnel's hand fatigue, and the use effect is improved. But in the same way, the matching and positioning mode of the limiting rod and the clamping groove adopted by the limiting mechanism still has the defect that the locking position of the hemostatic forceps is limited.

In summary, further optimization and improvement of the existing hemostat are urgently needed to improve the practical application effects of locking and head replacement, and provide convenience for medical operations.

SUMMERY OF THE UTILITY MODEL

For solving the not enough of background art existence, the utility model provides a dual-purpose medical hemostatic forceps with locking function, it can realize the locking after the centre gripping through the cooperation of locking cover and two gluey pieces to two rotatory supporting rods can carry out the switching of straight binding clip and curved binding clip, facilitate for the operation of medical treatment operation.

In order to achieve the above purpose, the utility model adopts the following technical proposal: the utility model provides a dual-purpose medical hemostatic forceps with locking function, includes pivot, locking cover, two tong arms, two supporting rods and two gluey pieces, two tong arm intermediate position cross arrangement and pass through the pivot is rotated and is connected, and two tong arm tail ends are provided with the ring respectively, and the shaft hole has transversely been seted up respectively on two tong arm tops, two supporting rod symmetries set up between two tong arm tops, and the supporting rod both ends set up respectively to straight binding clip and curved binding clip, and clamping rod outside central point puts the vertical fixation have the bolt and with correspond the shaft hole cartridge is connected, the bolt can be at the shaft hole internal rotation and lock the location, make the supporting rod rotate around the bolt will straight binding clip or curved binding clip stretches out two tong arm tops, and two tong arms are neighbouring the ring position outside is fixed with gluey pieces respectively, two gluey piece appearances are right angled triangle and inclined plane towards the outside, the locking cover can be dismantled and establish on two gluey pieces, and the locking cover both sides are the toper and arrange and are provided with two slope side arms, through removing the locking cover can tighten up two gluey pieces relatively under the guide of two slope side arms.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses be fixed with right angled triangle's gluey piece respectively in two tong arm afterbody outsides, the inclined plane of two gluey pieces is the toper and arranges, and the cooperation of locking cover both sides is provided with two slope side arms that are the toper equally and arrange, the accessible removes the locking cover behind the centre gripping and makes two gluey pieces tighten up gradually, thereby make hemostatic forceps realize the locking function, the doctor needn't last the holding action again, help developing smoothly of other operations, and two supporting rods have been installed additional on hemostatic forceps top, the supporting rod both ends set up respectively to straight binding clip and curved binding clip, two rotatory supporting rods can carry out the switching dualpurpose of straight hemostatic forceps and curved hemostatic forceps, the function is more comprehensive, facilitate for the operation of medical treatment operation, very high popularization and application value has.
