Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] Such as Figure 1-2 As shown, the vascular imaging search stick disclosed in the present invention includes a light-emitting part 1, a light guide column 2, a handheld part 3, and a light source 4. The light-emitting part 1 and the light source 4 are connected through the light guide column 2, and the light guide column 2 is connected to the hand-held part 3. The light source 4 is placed in the handle 3 .

[0030] Preferably, the light emitting part 1 includes a cylindrical part 12 , the cross section of the cylindrical part 12 is circular, and the bottom end of the cylindrical part 12 is connected with the light guide rod 2 .

[0031] Preferably, the diameter of the cylindrical portion 12 gradually decreases from the bottom end to the top end.

Abstract

The vascular imaging search stick disclosed by the invention belongs to the field of medical devices and includes a light emitting part (1), a light guide column (2), a hand-held part (3), and a light source (4). The light emitting part (1) and the light source (4) ) is connected through a light guide post (2), the light guide post (2) is connected to the hand-held part (3), and the light source (4) is placed in the hand-held part (3). When in use, place the search rod on the lower part of the retina, through the difference in light transmittance between the blood vessels and the tissue, you can clearly see the direction of the blood vessels, avoid damaging the blood vessels during the operation, and reserve more blood vessels on the retina for the patient , Intestinal survival plays an important role; it can also be used for exploration, stripping, and compression of deep tissues in the abdominal cavity to stop bleeding.

Description

technical field [0001] The invention relates to a medical device, in particular to a search rod for developing blood vessels. Background technique [0002] Intestinal resection will remove part of the greater omentum, and the distribution and direction of blood vessels in the greater omentum are often difficult to see clearly during the operation, and blood vessels are easily injured during the operation. Injuries to blood vessels during the operation have a great impact on the normal survival of the intestine and the motility function of the intestine. Contents of the invention [0003] The present invention aims to provide a vascular imaging search stick, which can clearly see the direction of blood vessels under direct vision when the search stick is placed in the lower part of the omentum, so as to avoid damage to blood vessels during operation. It plays an important role in preserving more blood vessels on the omentum and intestinal survival for the patient. It can ...
