Description

Cover refers to push broach

Affiliated technical field

This utility model relates to a kind of cover and refers to push broach, belongs to medical instruments field.

Background technology

At present, push broach commonly used in the surgical operation is the cutter head that shaft-like handle of a knife front end is circular arc, and there is curved blade the cutter head front side, and in use, with the tissue of curved blade contrectation cutting and separating, the patient holds handle of a knife and promotes forward, and tissue is cut.In operating some situation, the cutting and separating tissue that need to move under water under non-direct-view moves under water in the lacuna if use this moment traditional existing push broach to stretch into tissue, is difficult for accurately operation because can not look at straight, and the risk of accidentally injuring other tissues is arranged.Push broach in the existing medical apparatus and instruments improves type, not yet solves accurate cutting and separating destination organization and difficult problem of accidentally injuring surrounding tissue in human body moves under water lacuna.

Summary of the invention

In order to make things convenient for patient accurate cutting or chorista and the difficult surrounding tissue of accidentally injuring in human body moves under water lacuna, the technical program provides a kind of cover to refer to push broach, make in surgical operation, the solution push broach is stretched into to move under water in non-direct-view situation and is organized the problem that is difficult for accurate cutting and separating destination organization in the lacuna and easily accidentally injures surrounding tissue, thereby makes this step in the surgical operation more safe and quick.

The technical scheme that its technical problem that solves this utility model adopts is: this utility model comprises 5 parts: fingerstall 1., the push broach head 2., knife bar 3., reverse hold handle 4., stud connection 5..This utility model adds push broach as body design take fingerstall, with push broach head and the knife bar of blade, reverse and hold handle and form push broach, the knife bar front end continues mutually with hook-shaped cutter head, a push broach front side band blade (do not limit by a push broach cutting edge shape, can be circular arc, dihedral, oblique or craspedodrome etc.), back segment part at knife bar, reverse and hold handle be connected with knife bar (reverse hold the petioliform shape do not limit), fingerstall is with several hinge covers, the hinge cover can be placed in and form the hinge joint on the knife bar, and push broach is connected with fingerstall by the hinge joint.During use, operator partly is placed in the fingerstall in this utility model on the finger, reverse and hold handle with other fingers, make the push broach head be attached at fingerstall, stretching into human body with the finger of fingerstall moves under water and organizes in the lacuna, finger tip touches searching perception destination organization with referring to abdominal part, perception finger tip or when referring to that the abdominal part contact target is organized, other fingers reverse holds handle, the push broach head is erected from the fingerstall surface, and be vertical or near perpendicular to the fingerstall tangent plane, at finger tip or refer under the stereognosis guiding of abdomen, make the cutting of push broach blade contrectation, the tissue of sharp property separation, under the finger push strength effect with fingerstall (and/or reverse the strength effect of holding handle under in other finger push), the cutting of push broach sword or sharp property separate targets tissue; Behind the end of operation, other fingers reverse and hold handle, make the nose heave fingerstall that newly is attached at of push broach, withdraw to move under water with the finger of fingerstall and organize lacuna, overlap to refer to that billhook also withdraws from finger.Reach like this under finger stereognosis guiding push broach is accurately operated destination organization, and surrounding tissue is difficult for causing the purpose of accidental injury.

The beneficial effects of the utility model are, can guarantee to be difficult for accidentally injuring in the situation of its hetero-organization, accurately and quickly destination organization are carried out the cutting and separating operation, and are easy to use, simple in structure.

In the accompanying drawing 1.. fingerstall; 2.. the push broach head; 3.. knife bar; 4.. reverse and hold handle; 5.. stud connection.

The specific embodiment

In accompanying drawing utility model embodiment, several tubular sleeves that 1. fingerstall upward attaches and the knife bar of push broach be the anterior hinge joint that forms 3., thereby make the push broach head 2. 1. mutually close with fingerstall, 1. user is placed in fingerstall on the finger, 4. other fingers of user reverse holds handle, 3. makes the push broach head 2. be attached at fingerstall 1. by knife bar; The finger that user is worn fingerstall stretches into the interstice of moving under water, under finger tip and the stereognosis that refers to abdomen are guided, 2. the push broach head is placed the destination organization nearside of wish cutting, separation, 4. other fingers reverse holds handle, 3. make the push broach head 2. be vertical or near perpendicular to fingerstall 1. by knife bar, the blade that 2. the push broach head is gone up contacts with destination organization, under driving with the finger push power of fingerstall (and/or reverse the strength effect of holding handle under in other finger push), the cutting of push broach sword or separate targets tissue; To destination organization cutting or separate complete after, 4. other fingers of user reverse again holds handle, 3. makes the push broach head 2. again be attached at fingerstall 1. by knife bar, the user finger is withdrawn from the potential lacuna of organizing, and overlaps to refer to that push broach also withdraws from finger.Can guarantee that so push broach accurately operates destination organization under the guiding of finger stereognosis, and surrounding tissue is difficult for causing accidental injury.

Claims (1)

1. a cover refers to push broach, combined by fingerstall and push broach, push broach by cutter head, the knife bar of the place ahead band blade, reverse and hold handle and form, it is characterized in that: fingerstall is connected with push broach and becomes one.
