Description

Special-shaped object taking device for minimally invasive breast tumor surgery through axillary puncture

Technical Field

The utility model relates to a minimal access surgery apparatus field especially relates to a thing ware is got to dysmorphism that is used for breast tumour minimal access surgery through armpit puncture.

Background

Minimally invasive surgery on breast tumors is a common treatment for breast tumors. After the tumor is cut, the tumor needs to be taken out by an extractor, so that the infection of healthy tissues is avoided.

Unlike the abdominal cavity, the breast is located in the chest, and the skin of the chest is not suitable for puncturing.

And the chest is arc-shaped, so the straight rod-shaped extractor is not suitable for the operation process.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a thing ware is got to dysmorphism that is used for mammary gland tumour minimal access surgery through armpit puncture, can follow armpit puncture and laminating thorax curve will get the thing bag and send near mammary gland tumour to pack the thing and get the thing bag into, the former route returns to pull out externally, avoids haring chest skin.

In order to realize the purpose, the utility model adopts the technical scheme that: the special-shaped object taking device comprises a push-pull rod, an outer sleeve sleeved outside the push-pull rod, an elastic ring connected to the front end of the push-pull rod and an object taking bag connected with the elastic ring, wherein the edge of a bag opening of the object taking bag is outward rolled to form a bundle tight seam, the elastic ring is slidably arranged in the tight seam in a penetrating mode, a pull ring is arranged at the tail end of the push-pull rod, a handle is arranged on the outer wall of the tail end of the outer sleeve, the push-pull rod and the outer sleeve are both arc-shaped, the curvature of the push-pull rod is the same as that of the outer sleeve, and the length of the push-pull rod is larger than that of the outer sleeve.

As a preferred technical proposal of the utility model, the curvature of the push-pull rod and the outer sleeve is 0.1-0.3m^-1。

As an optimized technical scheme of the utility model, the handle sets up for the symmetry two rings on the outer wall of outer tube tail end.

As an optimized technical scheme of the utility model, the plane at handle place with the plane at outer tube place is parallel.

As an optimized technical scheme of the utility model, the plane at handle place with the plane coincidence at outer tube place.

As an optimized technical proposal of the utility model, the plane of the handle is vertical to the plane of the outer sleeve.

As a preferred technical proposal of the utility model, the structure of the utility model also comprises a puncture sheath which is arc-shaped and has the same curvature with the push-pull rod and the outer sleeve.

Adopt the produced beneficial effect of above-mentioned technical scheme to lie in: the utility model discloses the convex puncture sheath of cooperation uses, can follow armpit puncture and laminating thorax curve will get the thing bag and send near mammary gland tumour to pack the thing into and get the thing bag, the former route returns to pull out externally, avoids haring chest skin.

Fig. 2 is a schematic perspective view of a first embodiment of the present invention.

Fig. 3 is a schematic perspective view of a second embodiment of the present invention.

In the figure: 1. push-pull rod 2, outer tube 3, elastic ring 4, get thing bag 5, sack 6, pull ring 7, handle.

Detailed Description

Implementation mode one

Referring to fig. 1-2, the utility model discloses a specific embodiment's structure includes push-and-pull rod 1, cover at the outer tube 2 of push-and-pull rod 1 outside, connects at the elastic ring 3 of push-and-pull rod 1 front end and links to each other with elastic ring 3 gets thing bag 4, gets 5 marginal outward curls of sack of thing bag 4 and forms a bundle tight seam, and elastic ring 3 slides and wears to establish inside tightening seam, and the tail end of push-and-pull rod 1 sets up pull ring 6, sets up handle 7 on the outer wall of outer tube 2 tail ends, push-and-pull rod 1 and outer tube 2 are arc, and push-and-pull rod 1 is the same with the camber of outer tube 2, and the length of push-and-pull rod 1 is greater than the length of outer tube 2. The curvature of any position of the arc-shaped push-pull rod 1 and the curvature of any position of the outer sleeve 2 are the same, and the arc-shaped push-pull rod and the outer sleeve cannot block each other in the relative movement process.

The curvature of the push-pull rod 1 and the outer sleeve 2 is 0.1-0.3m^-1. According to different curvatures of the thorax of a human body, the object taking device with the push-pull rod 1 and the outer sleeve 2 with corresponding curvatures is selected.

The handle 7 is two rings symmetrically arranged on the outer wall of the tail end of the outer sleeve 2. The handle 7 is convenient for the forefinger and the middle finger to hold.

The plane of the handle 7 is coincident with the plane of the outer sleeve 2.

Second embodiment

Referring to fig. 3 alone, the handle 7 lies in a plane perpendicular to the plane of the outer sleeve 2.

The angles of the handles 7 of the two embodiments are different, so that doctors with different use habits can choose the handles.

The utility model discloses a theory of operation is: before use, the elastic rings 3 are combined together and accommodated in the outer sleeve 2 together with the object-taking bag 4. When in use, the arc puncture sheath penetrates from the armpit of a patient and is attached to the thoracic curve to reach the position near the breast tumor, and a channel is formed between the puncture inlet of the armpit and the breast tumor; then the front end of the outer sleeve 2 of the extractor is penetrated into the puncture sheath and reaches the vicinity of the breast tumor along the channel; keeping the outer sleeve 2 fixed, simultaneously pushing the push-pull rod 1 forwards to push the elastic ring 3 and the object taking bag 4 out of the outer sleeve 2, wherein the elastic ring 3 has metal memory and can be automatically unfolded into a circular ring shape without the restraint of the outer sleeve 2, and the bag opening 5 of the object taking bag 4 is then opened; the breast tumor is cut off and put into the object taking bag 4, the pull-push rod 1 is pulled back through the pull ring 6, the elastic rings 3 are combined again under the restraint of the tube wall of the outer sleeve 2, meanwhile, the bag opening of the object taking bag 4 cannot be retracted into the outer sleeve 2 due to the blockage of the outer sleeve 2 and has to be closed, and finally, the whole object taking device is taken out in the original way, so that the operation can be completed.

The whole operation process avoids puncturing from the chest and avoids damaging the chest skin.

The above description is only given as an enabling solution for the present invention and not as a single limitation on the solution itself.
