Description

Technical Field

[0001] The invention relates to the field of medical instruments, in particular to a scalp hemostatic gun. Background Art

[0002] In clinical brain surgery, a large number of scalp clamps are needed to fix and stop bleeding of the patient's cut scalp. Multiple scalp clamps are needed for a brain surgery at the same time. The current operation methods are mainly divided into two types: one is the traditional scalp clamp, which uses scalp clamps to clamp the scalp clamps one by one and then clamp them again. In this way, doctors and nurses need to repeatedly pass the scalp clamps, which is time-consuming and labor-intensive, and will increase the patient's bleeding and prolong the operation time. The other is a continuous-fire scalp clamp, which can be pre-loaded into the scalp clamp magazine before the operation. After the scalp is cut, the scalp clamps are fired continuously and quickly to clamp the scalp to be clamped. However, the gun body and magazine of the existing continuous-fire scalp clamp are prone to problems such as direct force deformation of the upper surface of the magazine shell and the magazine moving forward when firing, which in turn causes the scalp clamp to fire unsmoothly or even fail to fire. Summary of the invention

[0003] The main technical problem solved by the present invention is to provide a scalp hemostatic gun, which can limit the magazine assembly to avoid movement during the firing process and solve the problem of being unable to fire.

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 and Figure 2 A scalp hemostatic gun comprises a gun body 1 and a magazine assembly 2 mounted on the gun body 1, a firing assembly 3 is mounted in the gun body 1, the magazine assembly 2 comprises a shell 21 and a push clamp plate 22 movably mounted in the shell 21, a plurality of scalp clips are mounted in the push clamp plate 22, the firing assembly 3 is cooperatively connected with the push clamp plate 22 to fire the scalp clips, a block 211 is provided on the shell 21, a baffle plate 11 is provided on the gun body 1, and the shell 21 is mounted on the gun body 1 so that the block 211 abuts against the rear side of the baffle plate 11.

[0025] like Figure 3 and Figure 4, the block 211 is located on the lower surface of the housing 21. A groove 212 is symmetrically provided on the lower surface of the housing 1 in the axial direction, and the block 211 is located on the outer side of the groove 212 and is symmetrically arranged in the axial direction. A lower inclined surface 213 is provided between the lower surface and the left and right side surfaces of the housing 21, and the block 211 is located on the lower inclined surface 213 and is arranged in the vertical direction. The forward movement of the magazine assembly 2 is effectively limited by the baffle 11 and the block 211, so that the magazine assembly 2 can be prevented from moving forward and backward when the firing assembly 3 is fired, thereby solving the problem of failure to fire.

[0026] The positions of the block 211 and the baffle 11 can be adjusted according to the structure of the housing 21 and the gun body 1. The block 211 is not limited to being arranged at the bottom of the housing 21, but can also be arranged on the left and right sides of the housing 21. The block 211 can also be arranged in front of or behind the slot 212, and the two blocks 211 can be a left-right split structure or connected into an integral structure.

[0027] like Figure 3 In addition, the upper end surface of the rear part of the shell 21 has a supporting wing 214, and the rear part of the upper end of the gun body 1 is movably provided with a safety block 12, and the two ends of the safety block 12 are pressed on the supporting wing 214, so that the shell 21 is firmly connected to the gun body 1. An upper inclined surface 214 is provided between the lower surface and the left and right side surfaces of the shell 1, and the supporting wing 214 is located on the upper inclined surface. The left and right sides of the safety block 12 have downwardly extending pressing parts 121, and the pressing parts 121 are pressed on the upper surface of the supporting wing 214. The safety block 12 is pressed on the supporting wing 214, and the pressing force is dispersed on the upper surface of the supporting wing 214 to solve the problem of deformation of the transparent shell 21 under stress. This structure can prevent the safety block 12 from being directly pressed on the shell 21, thereby avoiding the phenomenon that the shell 21 is deformed under stress during firing, which makes the firing not smooth.

[0028] In addition, the gun body 1 has a mounting plate 13 , the housing 21 is arranged on the inner side of the mounting plate 13 , the baffle is located at the bottom of the mounting plate 13 , and the safety block 12 is movably connected above the mounting plate 13 .

[0029] like Figure 5 In addition, the inner side of the push clamp plate 22 is also provided with a backstop bar 23, on which a plurality of inwardly protruding blocks are evenly spaced in sequence. The blocks are engaged with the scalp clamp to limit the retreat of the scalp clamp. The backstop bar is provided with a hook, which is engaged with the slot on the outer shell to fix the backstop bar.

[0030] like Figure 6 In addition, a connecting hook 216 is provided at the lower end of the shell 21 , and a rotating shaft is provided on the gun body 1 . The connecting hook 216 is engaged with the rotating shaft so that the shell 21 rotates around the gun body 1 .

[0031] The firing assembly includes a firing handle 31, a connecting rod 32 and a firing gear 33. The firing handle 31 is connected to the firing gear 33 through the connecting rod 32. A tooth groove is provided on the push clamp plate 22. The firing gear 33 passes through the groove body 212 of the shell 21 and meshes with the tooth groove. The firing handle 31 drives the connecting rod 32 to rotate the firing gear 33 to drive the push clamp plate 22 forward. The rear end of the firing gear 33 is connected to a tension spring 34, and the other end of the tension spring 34 is connected to the gun body 1. The tension spring 34 is used to drive the firing gear 33 to reset.

[0032] Different from the prior art, the scalp hemostatic gun of the present invention uses the block of the magazine assembly and the baffle on the gun body to prevent the magazine from moving during the firing process, and uses the supporting side wings on the outer shell to withstand the pressure of the safety block, thereby preventing the safety block from directly pressing on the outer shell and causing the upper surface of the outer shell to be deformed due to force.

[0033] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
