Abstract
The utility model discloses a both-side-thrusting structure of a thrust handle of a linear cutting stapler. The both-side-thrusting structure comprises the thrust handle (1), a cutting assembly frame (5) and a thrust block (2), wherein the thrust handle (1) is connected with a thrust block (2) in rotary mode, the thrust block (2) is movably arranged in the cutting assembly frame (5), a safety block (4) is arranged in a groove hole (2-1) of the thrust block (2), an elastic part is arranged between the safety block (4) and the thrust block (2), a long groove (5-1) matched with the upper end of the safety block (4) is arranged on the cutting assembly frame (5), and two positioning grooves (1-1) matched with the lower end of the safety block (4) are symmetrically arranged on the thrust handle (1). The thrust handle has the function of thrusting from both sides.
Description
Technical field
This utility model relates to a kind of propelling handle both sides push structure of linear cutting anastomat, belongs to medical instruments field.
Background technology
At present, reflection clinically has the one-sided propulsive linear cutting anastomat of the handle of propelling; No problem though perform an operation; But the doctor does not advance at opposite side and selects, and can bring the inconvenience of operation, so be badly in need of a kind of propelling handle both sides push structure of linear cutting anastomat.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art, and a kind of propelling handle both sides push structure that advances the propulsive linear cutting anastomat in handle ability both sides is provided.
The technical scheme that realizes this utility model purpose is: a kind of propelling handle both sides push structure of linear cutting anastomat; It comprises propelling handle and cutting assembly frame; Also comprise forward block, advance handle rotatably to be connected with forward block, forward block is installed in the cutting assembly frame movably; In the slotted eye of forward block safety block is installed; Be provided with elastic component between safety block and the forward block, have the elongated slot that cooperates with the safety block upper end on the cutting assembly frame, advance on the handle and have two locating slots that cooperate with the safety block lower end symmetrically.
Further, described elastic component is a spring.
Further, described safety block is provided with first shoulder, is provided with second shoulder in the described slotted eye, and described spring housing is contained on the safety block, and an end of spring props up first step, and the other end props up second step.
After having adopted technique scheme, the safety block lower end is stuck in the locating slot that advances handle, advances handle to be positioned at a side; Advance handle when promoting, to drive forward block and travel forward, when advancing the handle rollback, drive the forward block rollback; When returning back to home, spring resets to the safety block upper end in the elongated slot of cutting assembly frame, and the safety block lower end has just broken away from the locating slot that advances handle; Advance handle just can rotate freely this moment; The operator just can select to advance handle to be positioned at which side, advances the propulsive requirement in handle both sides thereby reach, and has made things convenient for the operation of operation.

The specific embodiment
For the content that makes this utility model is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, this utility model is done further detailed explanation,
Shown in Fig. 1 ~ 5; A kind of propelling handle both sides push structure of linear cutting anastomat, it comprises propelling handle 1 and cutting assembly frame 5, also comprises forward block 2; Advance handle 1 rotatably to be connected with forward block 2; Forward block 2 is installed in the cutting assembly frame 5 movably, in the slotted eye 2-1 of forward block 2 safety block 4 is installed, and is provided with elastic component between safety block 4 and the forward block 2; Have the elongated slot 5-1 that cooperates with safety block 4 upper ends on the cutting assembly frame 5, advance on the handle 1 and have two locating slot 1-1 that cooperate with safety block 4 lower ends symmetrically.Described elastic component is a spring 3.Described safety block 4 is provided with the first shoulder 4-1, is provided with the second shoulder 2-1-1 in the described slotted eye 2-1, and described spring 3 is sleeved on the safety block 4, and an end of spring 3 props up first step 4-1, and the other end props up second step 2-1-1.
The operation principle of this utility model is following:
Safety block 4 lower ends are stuck among the locating slot 1-1 who advances handle 1, advance handle 1 to be positioned at a side, advance handle 1 when promoting, to drive forward block 2 and travel forward; When advancing handle 1 rollback, drive forward block 2 rollbacks, when returning back to home; Spring 3 resets to safety block 4 upper ends in the elongated slot 5-1 of cutting assembly frame 5; Safety block 4 lower ends have just broken away from the locating slot 1-1 that advances handle 1, and advance handle 1 just can rotate freely this moment, and the operator just can select to advance handle 1 to be positioned at which side; Advance the propulsive requirement in handle both sides thereby reach, made things convenient for the operation of operation.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to this utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of this utility model; Be not limited to this utility model; All within the spirit and principle of this utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of this utility model.
