CN102772848A - Attaching clamp for cardiovascular operation cannula - Google Patents

Abstract

The invention relates to a medical device, in particular to an attaching clamp for a cardiovascular operation cannula. The attaching clamp for the cardiovascular operation cannula consists of a clamp bucket, a sleeve, an upper handle, a spring, a blind nut, two guiding shafts and a lower handle. The clamp bucket is an inverted circular truncated cone body without an upper bottom surface or a lower bottom surface; one end of the upper handle is combined with the clamp bucket. The side wall of the sleeve is provided with the elongated lower handle which is integral with the sleeve. The two guiding shafts vertically penetrate the upper handle and the lower handle and form a movable fit relation with the upper handle; the same horizontal positions of the upper handle and the lower handle between the two guiding shafts are respectively provided with a disk body. The spring is arranged between the two disk bodies. The cannula not only firmly fixed by the attaching clamp for the cardiovascular operation cannula but also can be delivered to a deeper position, thus, the operation accuracy and the operation stability are greatly improved.

Description

Operation on vessels of heart intubate fixation clamp

Technical field

The present invention relates to a kind of medical apparatus and instruments, particularly relate to a kind of operation on vessels of heart intubate fixation clamp.

Background technology

In heart or trunk operation, usually need carry out intubate to blood vessel, be directly to take pipe to carry out intubate entirely in the present operation with hands, when operating for the deep, hands can't put in the otch deep.At this moment, because pipe is softer, and handgrip part is far away from tip, and the accuracy of intubate is greatly affected.

Summary of the invention

The present invention provides a kind of operation on vessels of heart intubate fixation clamp of ability stable holding intubate for solving the deficiency of prior art.

The scheme that solves technical problem of the present invention is: operation on vessels of heart intubate fixation clamp is made up of clam(shell) bucket, sleeve, last handle, spring, nut, the axis of guide and following handle.Clam(shell) bucket is a rounding stage body supreme, bottom surface, and an end of the last handle of strip combines as a whole with clam(shell) bucket.Sleeve is a cylindrical shape, and having on the telescopic sidewall with sleeve is the following handle of holistic strip.The axis of guide is that upper and lower side all has the screwed round bar of die and lower end, and two axis of guides vertically run through handle and are in active relationship with following handle and with last handle, and the lower end of the every axis of guide is with nut.On the last handle between two axis of guides and the par position of following handle a disc is arranged all.Have between said two discs upper and lower end respectively with the spring of said disc welding.During use, only need the upper end of intubate is inserted in the sleeve, the upper end that makes intubate will be gone up handle again and hold together to pinch with following handle is past with telescopic suitable for reading concordant, and clam(shell) bucket promptly inserts in the sleeve, and clam(shell) bucket and sleeve are fixed the upper end of intubate.

Adopt such scheme, can reach following effect:

Because clam(shell) bucket and sleeve can be clamped the intubate upper end firmly; And sleeve has also played reinforcement effect to softer intubate; Therefore the present invention can not only fixedly secure intubate, and can intubate be sent to than the position, deep, has improved the accuracy and the stability of operation greatly.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is done further description.

Operation on vessels of heart intubate fixation clamp is made up of clam(shell) bucket 1,sleeve 2,last handle 3, spring 4, nut 5, the axis ofguide 6 and following handle 7.Clam(shell) bucket 1 is a rounding stage body supreme, bottom surface, and an end of thelast handle 3 of strip combines as a whole with clam(shell) bucket 1.Sleeve 2 is a cylindrical shape, has on the sidewall ofsleeve 2 withsleeve 2 to be the followinghandle 7 of holistic strip.The axis ofguide 6 is that upper and lower side all has the screwed round bar of die and lower end, and two axis ofguides 6 vertically run throughhandle 3 and are in active relationship with followinghandle 7 and withlast handle 3, and the lower end of the every axis ofguide 6 is with nut 5.On thelast handle 3 between two axis ofguides 6 and the par position of followinghandle 7 disc is arranged all.Have between said two discs upper and lower end respectively with the spring of said disc welding.During use, only need the upper end of intubate is inserted in thesleeve 2, the upper end that makes intubate is suitable for reading concordant withsleeve 2, will go up thathandle 3 and followinghandle 7 are past to be held together to pinch again, and clam(shell) bucket 1 promptly inserts in thesleeve 2, and clam(shell) bucket 1 andsleeve 2 are fixed the upper end of intubate.

Claims (1)

1. an operation on vessels of heart intubate fixation clamp is made up of clam(shell) bucket, sleeve, last handle, spring, nut, the axis of guide and following handle; It is characterized in that: clam(shell) bucket is a rounding stage body supreme, bottom surface; One end of the last handle of strip combines as a whole with clam(shell) bucket; Sleeve is a cylindrical shape, and having on the telescopic sidewall with sleeve is the following handle of holistic strip, and the axis of guide is that upper and lower side all has the screwed round bar of die and lower end; Two axis of guides vertically run through handle and are in active relationship with following handle and with last handle; The lower end of the every axis of guide is with nut, on the last handle between two axis of guides and the par position of following handle a disc is arranged all, the spring that has upper and lower end to weld with said disc respectively between said two discs.
