Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The first embodiment is as follows:

as shown in fig. 1 and 9, the utility model relates to a clip applier with a percussion device, which comprises a sleeve 1, wherein the head of the sleeve 1 is provided with a binding clip 2, the tail is provided with a clamp handle 3, and the middle is provided with a fixed rod 4 which is fixedly connected.

The tail of the sleeve 1 is also provided with a fixed shell, the forceps handle 3 comprises a fixed forceps handle 31 and a movable forceps handle 32, the fixed forceps handle 31 is fixedly connected with the shell, and the movable forceps handle 32 is hinged with the shell through a hinge shaft 8.

The binding clip 2 comprises two symmetrically arranged binding clip mouths, the tail parts of the binding clip mouths are hinged with the head parts of the fixed rods 4, and the head parts of the binding clip mouths are elastically connected through elastic sheets.

The head of sleeve pipe 1 is provided with casing seat 5, and casing seat 5 is provided with the hole of flaring, and when sleeve pipe 1 moved to binding clip 2 direction, hole drive binding clip 2 was closed.

The movable clamp handle 32 is also fixedly connected with a percussion block 6 at the other side of the articulated shaft 8, and the movable end of the percussion block 6 is U-shaped and is clamped at the two sides of the fixed rod 4.

When the movable clamp handle 32 is closed, the sleeve 1 extends out, and the clamp head 2 is closed; when the movable clamp handle 32 is opened, the fixed rod 4 is contracted, and the clamp head 2 is opened.

The fixing rod 4 in the utility model is fixed, the opening and closing of the binding clip 2 are realized by the axial movement of the driving sleeve 1, the traditional mode that the opening and closing of the binding clip 2 are realized by the driving fixing rod 4 is replaced, and the forced deformation of the fixing rod 4 is avoided; moreover, the sleeve 1 is more stable in structure relative to the fixed rod 4, thereby ensuring the utility model has safe and reliable use and safe operation.

Example two:

compared with the first embodiment, the differences are as follows: as shown in fig. 2, 3 and 5, the sleeve 1 is provided with a plurality of chucking plates 11. The clamping plate 11 points to the forceps handle 3 and inclines towards the inner side of the sleeve 1; the socket 5 is provided with a bayonet 51 for engaging the catch plate 11. The manufacturing process of the clamping plate 11 comprises the following steps: the sleeve 1 is first cut with a U-shaped slit and then the catch plate 11 is driven to bend. Above-mentioned setting, the mode installation of casing seat 5 through the joint, easy operation is convenient.

Example three:

compared with the two examples, the difference is that: as shown in fig. 13 and 14, the cannula holder 5 is provided with two symmetrically arranged plugboards 52 for plugging the cannula 1, and the bayonet 51 is arranged on the plugboards 52; the inner side of the plug board 52 is provided with an inclined plane, and the two inclined planes form a flaring inner hole of the sleeve seat 5; the inner side of the inserting plate 52 is also provided with a guide block 53; as shown in fig. 12, the binding clip 2 is composed of two symmetrically arranged binding clip mouths, and the tail of the binding clip mouth is provided with a sliding groove 21 for clamping a guide block 53, so that the sleeve 1 is movably guided, and the sleeve 1 is prevented from rotating.

Example four:

compared with the first embodiment, the differences are as follows: as shown in fig. 6, the tail part of the sleeve 1 is provided with a first convex ring 41 and a second convex ring 42, and the movable end of the firing block 6 is arranged between the first convex ring 41 and the second convex ring 42. Since the conventional trigger block 6 drives the sleeve 1 by static friction force with the sleeve 1, and a slip occurs, which results in unstable movement of the sleeve 1, the trigger block 6 drives the first protruding ring 41 or the second protruding ring 42, so that the fixing rod 4 moves more stably.

Example five:

compared with the fourth embodiment, the differences are as follows: as shown in fig. 7 and 8, a movable block 33 is further led out from the movable clamp handle 32 in a direction opposite to the hinge shaft 8, and two sides of the movable block 33 are provided with limit grooves 34; the firing block 6 is composed of two symmetrically arranged firing plates 61, the firing plates 61 are hinged through a hinge shaft 8, and the hinged ends of the firing plates are inserted into the limiting grooves 34. So set up, not only simple structure, simple to operate moreover.

Example six:

compared with the four phases of the embodiment, the differences are as follows: as shown in fig. 3, 4, 10 and 11, the fixed sleeve 10 is fixedly connected to the tail of the sleeve 1, a ring plate is disposed at one end of the inner wall of the fixed sleeve 10, which is located at the forceps head 2, and a spring 7 connected to the sleeve 1 is connected between the ring plate and the first convex ring 41. Thus, the movable clamp handle 32 can be reset by the restoring force of the spring 7.

Example seven:

compared with the fifth embodiment, the differences are as follows: as shown in fig. 6, the housing is further connected with a limit bolt 9 through a thread, and the thread end of the limit bolt is opposite to the movable block 33. The closing amplitude of the movable clamp handle 32 is limited by adjusting the thread depth of the limit bolt 9. When a doctor holds the forceps handle 3 to enable the sleeve 1 to extend out to drive the forceps head 2 to be closed, the sleeve 1 is easy to damage the forceps head 2 due to the fact that the force is too strong, and therefore the technical problem is solved through the arrangement.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
