Multi-head measuring device for blood vessel calibers

Abstract

The invention discloses a multi-head measuring device for blood vessel calibers. The multi-head measuring device includes a shell and a plurality of measuring cores with different specifications; theshell comprises a cap body, a hold rod and a tip which are connected in sequence in a threaded mode, a plurality of slide grooves are formed in the cap body, and a measuring hole is formed in the endof the tip; the measuring cores are arranged symmetrically inside the shell, and the measuring cores include measuring columns and measuring heads; the measuring heads are arranged at one ends of themeasuring columns, and the diameter of the measuring heads of the measuring cores is different; control blocks are arranged at the other ends of the measuring columns; each control block penetrates the corresponding slide groove and is arranged outside the cap body; and the control blocks can slide in the slide grooves, and the corresponding measuring head can protrude from the measuring hole by pressing the corresponding control block. Compared with existing single measuring rulers, the multi-head measuring device can be used for the measurement of blood vessel calibers during oral and maxillofacial surgery, and is especially suitable for operations with relatively narrow operating space, so that the problem that a front caliber ruler hinders the measurement of a rear ruler during use issolved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary tools for surgery, and relates to a multi-head measuring device for blood vessel calibers. Background technique [0002] In September 1972, Harii et al. reported the success of anastomotic vascular flap transplantation, and the reports at home and abroad have gradually increased. The rapid development of basic research and anatomical research related to skin flaps has played a positive role in promoting the search for new flap donor sites. According to preliminary statistics, there are more than 50 skin and musculocutaneous flaps that can be harvested from the whole body. It is widely used in clinical practice, but requires high technical requirements, and there is still a certain failure rate. The indications should be strictly controlled. It is mainly applicable to: ① Exposed deep tissues such as muscles, tendons, nerves, and bones due to trauma or resection of low-grade malignant tumors Wou...

Problems solved by technology

[0003] In order to solve the problem that different caliber scales interfere with each other when measuring blood vessel caliber during surgery, the present invention provides a multi-head measuring device for vascular caliber. The measuring instrument can select different measuring heads for measurement according to requirements when measuring vascular caliber. Avoid reciprocating replacement of different measuring rulers, improve operation efficiency
