Description

Lymph node suction fixator

Technical Field

The utility model relates to a medical equipment field, concretely relates to lymph gland attracts fixer.

Background

Clinical surgery, especially tumor surgery, needs to clean lymph nodes regularly, and in practical operation, the lymph nodes are usually cut by clamping the lymph nodes with some kind of instrument, but the lymph nodes have the characteristic of being soft, and basically cannot form a relatively stable shape, and especially the shape change of the lymph nodes is extremely unstable under the action of external force, so that the lymph nodes are difficult to remove. The lymph nodes are extremely easy to break under the action of external force in the operation, and the lymph nodes are not allowed to be extruded by the external force in the operation, otherwise, the cancer cells of the lymph nodes are easy to promote to form reverse micrometastasis. At present, the commonly used lymph node forceps are used for cleaning lymph nodes, but the internal space of the clamping part is relatively fixed, so when the specification and the size are not very accurate, the lymph nodes are easily extruded or extruded and broken in two hemispherical shells, once the lymph nodes are broken, tumor cells in the lymph nodes can spread to other tissues, and some unnecessary troubles are added to an operator.

SUMMERY OF THE UTILITY MODEL

In order to overcome the deficiency of the background art, the utility model provides a lymph gland suction fixer mainly solves the present problem that lacks the centre gripping instrument that can better use when cleaning the lymph gland.

The utility model discloses a concrete implementation scheme does:

the utility model provides a lymph gland suction fixator, includes the casing, be equipped with the first air flue of being connected with the air supply in the casing, the casing front end is equipped with the shrink cover of being made by soft material, be equipped with in the shrink cover with the second air flue of first air flue intercommunication.

The shrink cover is a horn-shaped structure with a large lower part and a small upper part.

The shell is provided with a control valve which is arranged opposite to the first air passage.

The shrink cover comprises a hollow upper ring and a hollow lower ring, and a communicating pipe is arranged between the upper ring and the lower ring.

The inner wall of the shrink cover is provided with a bulge used for contacting with the lymph node.

The bulges are of sucker-shaped structures.

The shell is further provided with a sleeve in movable fit, and the sleeve comprises a first position and a second position, wherein the first position is arranged outside the shrink cover, and the second position enables the shrink cover to be exposed after movement.

The casing axial is equipped with the holding tank, be equipped with in the holding tank the sleeve pipe, the holding tank bottom with be equipped with the elastic component between the sleeve pipe.

The elastic piece is a spring.

The sleeve is provided with an operation block which extends out of the shell and is used for manual operation.

The utility model has the advantages that: the utility model provides a lymph gland suction fixing device, absorption that can be convenient is outside the lymph gland, is difficult to harm the lymph gland, the subsequent operation of being convenient for.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, the lymph node suction fixator comprises a shell 1, wherein a first air passage 2 connected with an air source is arranged in the shell, a shrink cover 3 made of soft materials is arranged at the front end of the shell, and a second air passage 31 communicated with the first air passage is arranged in the shrink cover. When the flexible material is used, the inner wall of the shrinkage cover is contacted with the lymph nodes by collecting the shrinkage cover through a negative pressure air source, and the flexible material can be silica gel, rubber and the like.

In this embodiment, as shown in the figure, the shrink hood is a horn-shaped structure with a large bottom and a small top.

In this embodiment, as shown in the figure, a control valve 4 is provided on the housing, opposite to the first air passage. The control valve can control the opening and closing of the first air passage and the size of the air quantity.

In this embodiment, as shown, the shrink hood comprises a hollow upper ring 32 and a lower ring 33, between which a communication pipe 34 is provided. The upper ring is provided with a plurality of air inlets 321, and the shell can be provided with a connecting pipe 111, and the air inlets are sleeved on the connecting pipe to complete connection.

In this embodiment, the inner wall of the shrink hood is provided with protrusions 35 for contacting the lymph nodes, as shown. The friction force upon contact with the lymph nodes can be increased.

In this embodiment, the protrusions are suction cup-like structures, as shown. Further increasing the frictional force of their contact.

In this embodiment, as shown in the figure, the casing is further provided with a movably-fitted sleeve 5, and the sleeve includes a first position outside the shrink cover and a second position exposing the shrink cover after moving. Before reaching the position of the lymph node, the sleeve is in the first position, the contraction cover is extended out after reaching the position of the lymph node, the use is convenient, and if necessary, a positive pressure air source can be filled to reset the contraction cover.

In this embodiment, as shown in the figure, the housing is axially provided with a receiving groove 11, the sleeve 5 is arranged in the receiving groove, and an elastic member 12 is arranged between the bottom of the receiving groove and the sleeve. The elastic piece can adopt a spring or a shrapnel and the like, under the conventional state, the sleeve extends out of the shell under the elastic force action of the spring, and after the sleeve is positioned, the sleeve is manually operated to overcome the elastic force to retreat.

In this embodiment, as shown, the elastic member is a spring.

In this embodiment, as shown, the sleeve is provided with an operation block 51 extending out of the housing for manual operation. The shell is provided with a long groove corresponding to the operation block.
