Description

Tumor positioning device

Technical Field

The utility model relates to a tumour positioner.

Background

Tumor tissue differs from normal tissue from which it originates to a different extent, both in cell morphology and tissue structure, and this difference is called heterogeneity. The heterogeneity is the morphological manifestation of abnormal differentiation of tumors. Small heterogeneity, indicating high degree of differentiation, large heterogeneity, indicating low degree of differentiation. The difference in size of this abnormal shape is the main histological basis for diagnosing tumors and determining their benign and malignant properties. The heterogeneity of benign tumor cells is not obvious and is generally similar to the tissue from which they originate. Malignant tumors often have significant heterogeneity.

The majority of tumors are benign, and benign tumors are mainly resected. When the tumor is removed, particularly the larger tumor of an individual, a better operation visual field needs to be reserved, so that when the tumor is removed, the tumor needs to be lifted upwards by means of external equipment, and the operation visual field is conveniently exposed.

The existing method is to use a simple positioning clamp, but when the positioning clamp clamps the tumor, the tumor is very easy to break or slip, and the operation is relatively unreliable.

Based on the problems, the tumor positioning device can be clamped through a plurality of positions, can realize positioning aiming at circular or special-shaped tumors, and can conveniently lift the tumor to flow out of a clear operation visual field.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a can carry out the centre gripping through a plurality of positions is provided, all can realize the location to circular or special-shaped tumour, conveniently lift the tumour positioner that flows out the clear operation field of vision behind the tumour.

The utility model discloses a realize through following technical scheme:

a tumor positioning device comprises an end part, wherein more than three rod pieces are annularly arranged on the outer wall of the end part, external thread parts are processed on the rod pieces, clamping plates are matched with the rod pieces, each clamping plate is provided with a hole for penetrating through the rod piece, the rod pieces are matched with nuts after penetrating through the clamping plates, the lower ends of the clamping plates are bent inwards to form inclined limiting plates, the thickness of the limiting plates is gradually reduced downwards, and the lower ends of the limiting plates are vertically bent to form hook parts; and a handle is processed and formed at the upper end of the end part.

Preferably, a rubber-made stopper washer is disposed between the nut and the chuck plate.

Preferably, a handle sleeve made of rubber is sleeved on the handle, and a handle groove is formed in the outer wall of the handle sleeve in an injection molding mode.

Preferably, a threaded hole is formed in the bottom of the end portion, the threaded hole extends upwards into the handle, a bolt is matched in the threaded hole, and a conical tumor positioning cover is arranged at the lower end of the bolt.

Preferably, an air bag made of rubber is arranged in the tumor positioning cover, and a hollow cavity is arranged in the air bag; the setting of gasbag can with the tumour between soft contact, the gasbag is deformable simultaneously, when the gas in the gasbag is not sufficient, can carry out deformation according to the appearance of tumour, increases the stability of centre gripping.

Preferably, an inwardly concave tumor locating notch is provided at the bottom of the balloon; the tumor locating notch can better locate the tumor.

The utility model has the advantages that: in this product, be provided with a plurality of cardboards, can follow the periphery of tumour through a plurality of cardboards and realize the multiple spot location, we can adjust the position of cardboard through adjusting nut's position, utilize the position control of a plurality of cardboards, realize the clamp of tumour tissue, utilize the handle to lift the tumour, let the border of tumour clear, make things convenient for the operation excision. The structure of this product is comparatively simple, and the cost is comparatively cheap, is fit for using widely.
