Description

Clip applier with safety device

Technical Field

The utility model relates to the technical field of medical equipment, specifically a execute clamp with safeties.

Background

Clip applier is a surgical instrument used to perform a clipping operation on a tissue clip, typically a V-clip, including titanium clips, non-absorbable clips, etc., during a surgical procedure.

The safety device of the existing clip applier in the current market is of a key type, and in the operation process, due to the fact that the distance between a trigger handle and an unlocking/locking key is too short, the error operation of the clip applier caused by the fact that the trigger handle is touched by mistake easily can cause the unlocking/locking of the clip applier in advance, and the operation can not be continued. The doctor needs to press the key again to complete the operation, which prolongs the operation time and affects the operation effect.

SUMMERY OF THE UTILITY MODEL

For solving the technical problem in the background art, the utility model discloses a execute clamp with safeties.

The utility model provides a clip applier with a safety device, which comprises a sleeve, a push rod is inserted in the sleeve, a binding clip is arranged at the head part, a clip handle is arranged at the tail part, the clip handle drives the push rod to move, the opening and closing of the binding clip are realized,

the push rod is provided with a clamping piece for clamping or separating from the sleeve;

the clamping piece is located at a position close to the clamp head.

The clamping piece is arranged at a position far away from the forceps handle, so that a doctor can not operate the clamping piece by mistake when operating the forceps handle, the operation safety is ensured, and the use is safe and reliable.

The concrete structure of joint spare joint sleeve pipe does: the sleeve pipe is provided with a bayonet, the clamping piece is provided with a clamping plate, and the clamping plate is clamped or separated from the bayonet under the driving action.

The traditional clamping piece is installed in a hinged mode, the process is complex, the manufacturing cost is high, the problem is further solved in an improved mode, specifically, the push rod is provided with a placing groove, and the clamping piece is installed in the placing groove and is elastically connected with the push rod. The elastic connection of the clamping piece is used for resetting the clamping piece.

The clamping piece comprises a transverse plate, one end of the transverse plate is integrally connected with the clamping plate, and a right angle is formed between the transverse plate and the clamping plate; the transverse plate is further provided with an elastic sheet abutting against the placing groove.

The placing groove is arranged on the push rod, the installation of the push rod can be influenced, and the production cost of the push rod can be increased, so that the problem is further improved and solved.

The clamping piece is large in movement space and easy to displace in the pressing and resetting process, so that the clamping plate is staggered, and the clamping opening cannot be accurately clamped in the resetting process, so that the problem is further solved in an improved mode; the baffle forms the U-shaped groove with one of them lateral wall of standing groove, the diaphragm peg graft in the U-shaped groove.

The placing groove needs to provide a deformation space for the elastic sheet, so that the U-shaped groove is too wide, the radial movement space of the transverse plate in the sleeve is larger, and the transverse plate is unstable in position when being inserted into the U-shaped groove, so that the problem is further solved.

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, the utility model relates to a execute clamp with safeties, including sleeve pipe 1, its inside push rod 2 that pegs graft has, binding clip 3 is installed to the head, and the afterbody is installed and is pressed from both sides handle 4, and the removal of 4 drive push rods 2 of binding clip realizes that binding clip 3 opens and shuts.

As shown in fig. 2-6, the sleeve 1 is provided with a bayonet 11 at a position close to the binding clip 3. The push rod 2 is provided with a clamping piece 5 which comprises a transverse plate 52, and one end of the transverse plate 52 is provided with a clamping plate 51 which is integrally formed and connected, and forms a right angle.

Under normal conditions, the clamping plate 51 is clamped with the clamping opening 11, and the push rod 2 is locked and cannot move. When the tong head 3 needs to be opened, a tool is used for pressing the clamping plate 51 to be separated from the bayonet 11, so that the push rod 2 is unlocked.

The clamping piece 5 is arranged at a position far away from the forceps handle 4, so that a doctor can not operate the clamping piece 5 by mistake when operating the forceps handle 4, the operation safety is ensured, and the use is safe and reliable.

Example two:

compared with the first embodiment, the differences are as follows: the push rod 2 is provided with a placing groove 21, and the clamping piece 5 is installed in the placing groove 21. Because traditional joint spare 5 adopts the installation of articulated mode, the process is more complicated, and manufacturing cost is also high, and consequently 5 installations of joint spare of being convenient for are placed in the setting of standing groove 21.

The back of the transverse plate 52 is also provided with a spring plate 53, and the spring plate 53 abuts against the bottom of the placing groove 21 to realize elastic connection. The spring piece 53 is used for resetting the clamping piece 5. The elastic piece 53 is convenient to install compared with a spring, and the position is more stable after installation.

Example three:

compared with the two examples, the difference is as follows: the front end of the push rod 2 is sleeved with a driving sleeve 6, and the placing groove 21 is arranged on the driving sleeve 6. So set up and solved traditional standing groove 21 and set up on push rod 2, push rod 2 not only installs the difficulty, technical problem that manufacturing cost is high moreover.

Example four:

compared with the three phases of the embodiment, the differences are as follows: the front end of the sleeve 1 is inserted with a fixed sleeve 7, and the fixed sleeve 7 is provided with a baffle 71; the baffle plate 71 and one side wall of the placing groove 21 form a U-shaped groove, and the transverse plate 52 is inserted into the U-shaped groove. Because the clamping piece 5 is pressed to reset, the movement space is large, and the displacement is easy to occur, so that the clamping plate 51 is staggered, and the clamping opening 11 can not be accurately clamped during resetting. Therefore, the U-shaped groove is used for limiting the moving space of the transverse plate 52 and guiding the movement of the transverse plate 52 to avoid the dislocation of the clamping plate 51.

Example five:

compared with the fourth embodiment, the differences are as follows: the bottom of the placing groove 21 is provided with a boss 22, and the baffle plate 71, the side wall of the placing groove 21 and the boss 22 form a U-shaped groove. Because the placing groove 21 needs to provide a deformation space for the elastic sheet 53, the U-shaped groove is too wide, the radial movement space of the transverse plate 52 in the sleeve 1 is large, and the position of the transverse plate 52 is unstable when the transverse plate is inserted into the U-shaped groove. Therefore, the technical problem is solved by the design.

Example six:

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 description, and must be determined according to the scope of the claims.
