Description

Technical Field

[0001] This application relates to the technical field of blood compression cut-off devices, and specifically discloses a medical large blood vessel blunt compression cut-off device with a detachable inner core. Background Art

[0002] During surgical operations, unplanned bleeding can cause the surgical field to be blocked by blood, affecting the judgment and operation of the surgeon. Bleeding from large blood vessels also poses risks such as shock and gas embolism. Therefore, planned blood flow interruption and timely hemostasis in case of unplanned bleeding are particularly important.

[0003] During surgical operations, during the process of severing, anastomosing, or separating large blood vessels, it is often necessary to temporarily block the blood flow of large blood vessels to avoid the outflowing blood interfering with the surgical field, so as to facilitate the operation of the surgeon. In some tumor resection surgeries, the surgeon also tends to choose to pre-block the blood flow of the large blood vessels leading to the tumor in order to reduce the amount of bleeding during the tumor resection process. At this time, the surgeon often tends to completely free the tissues and adhesions around the large blood vessels and then use "forceps" or "clamp" type instruments to clamp the large blood vessels. However, during the operation, it often occurs that the large blood vessels are difficult to free and expose, and cannot be completely clamped. At this time, a more ideal blood flow interruption method is to apply pressure on the surface of the large blood vessels. However, there is still a lack of large blood vessel pressurization devices or instruments that can effectively and safely compress large blood vessels to block blood flow.

[0004] In view of this, the inventor proposes a medical large blood vessel blunt compression cut-off device with a detachable inner core. Summary of the Invention

[0005] This solution aims to design a medical large blood vessel blunt compression cut-off device with a detachable inner core, which can timely and effectively complete the blood flow interruption of large blood vessels, and attempts to create a fast, safe, and convenient large blood vessel anastomosis environment through the design concept of "pulling out the inner core", reduce the damage to surrounding tissue organs during compression hemostasis, reduce the bleeding time and amount of bleeding, and shorten the operation duration.

[0006] To achieve the above object, the present invention provides the following basic solution:

[0007] Medical large blood vessel blunt compression cut-off device with a detachable inner core,

[0008] The principle and effect of this basic solution are as follows:

[0009] 1. Compared with the prior art, the structure of this device is simple, the concept is ingenious, and the transparent material design can conveniently observe the compression effect and control the pressing force while compressing and cutting off the blood flow of large blood vessels, specifically including: whether the compression is effective, whether there is still blood oozing, whether there is bleeding from small branch blood vessels, and whether excessive force is used to damage other tissue tracheas below the instrument.

[0010] 2. Compared with the prior art, the inner core of this instrument can be pulled out. When the inner core is not pulled out, the contact surface for compressing the large blood vessels can be increased, enhancing the compression and blocking effect. When the inner core is pulled out, other surgical instruments can pass through the central hollow part of the instrument to perform surgical operations on the blood vessels, tissues, and organs in the hollow part, such as suturing for hemostasis.

[0011] 3. The design of the hand-held fixing column enables the doctor to hold only one corner of the instrument to press down the instrument and block the blood flow, without obstructing the surgical field of view.

[0012] 4. A hemostatic instrument that is convenient to use is an important condition for successfully completing a surgical operation. Being able to quickly and effectively block the blood flow while avoiding damage to the surrounding tissues is a crucial step in many surgeries. And the structure of this patent is simple, the operation is convenient, and the operation risk is small; the transparent material facilitates the surgeon to observe the finger pressure situation; the hand-held movable pin can conveniently take out the hemostatic inner plate, which is beneficial for blood vessel repair; it can avoid large vein air embolism; it has a low cost, can be popularized, and has high economic benefits.

[0013] 5. This device has a wide range of applications and can be used in non-minimally invasive surgeries involving large blood vessels. Such as thoracic surgery, general surgery, urological surgery, gynecological and obstetric surgery, neurosurgery, etc.

[0014] Further, the inner core fixing device includes outer pin fixing bands symmetrically fixed on the outer groove, inner pin fixing bands fixed on the transparent inner core, and movable pins for realizing the sliding between the inner pin fixing bands and the outer pin fixing bands, achieving the detachable connection between the inner core and the outer groove.

[0015] Further, a magic tape that fits the skin is provided on the inner side of the outer groove away from the hand-held fixing column, facilitating the fixing and stability of the outer groove.

[0016] Further, a hand-held pin handle for restricting the position of the movable pin is provided on the movable pin.

[0017] Further, the outer groove is rectangular, and the long axis direction in the rectangular outer groove is consistent with the blood flow direction of the large blood vessel and perpendicular to the sliding direction of the movable pin, facilitating the blocking of blood flow.

[0018] Further, the middle of the outer groove is designed with a hollow for placing the inner core, and the inner core is designed as a pressing piece, which is used to increase the contact surface for compressing the large blood vessel when the inner core is not pulled out.

[0019] Further, the number of the hand-held fixing columns is four, anti-slip patterns are provided on the hand-held fixing columns, and the hand-held fixing columns are evenly distributed at the four corner positions of the outer groove, facilitating compression hemostasis.

[0020] Further, the height of the handheld latch handle is higher than that of the inner latch fixing belt and the outer latch fixing belt, and the movable latch is the same as the handheld fixing column, and both are provided with anti-slip patterns.

[0021] Further, the length of the handheld fixing column is greater than the width of the palm of a standard adult male. It is convenient to hold, and thus convenient for pressing to stop bleeding. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The reference numerals in the drawings of the specification include: outer groove 01, handheld fixing column 011, inner core 2, inner core fixing device 03, movable latch 031, handheld latch handle 032, inner latch fixing belt 033, outer latch fixing 034.

[0028] Embodiments are as Figure 1 、 Figure 2 and Figure 3 shown:

[0029] The inner core extractable medical large blood vessel blunt compression cutter includes an outer groove 01, a plurality of handheld fixing columns 011 fixedly connected to the periphery of the outer groove 01, a transparent inner core 2 detachably connected to the outer groove 01, and an inner core fixing device 03 for realizing the disassembly of the inner core 2.

[0030] Specifically: The number of the hand-held fixing columns 011 is four, and anti-slip patterns are provided on the hand-held fixing columns 011. The hand-held fixing columns 011 are evenly distributed at the four end corners of the outer groove 01. It is convenient for pressing to stop bleeding. The length of the hand-held fixing column 011 is greater than the width of the palm of a standard adult man. It is convenient to hold, and thus convenient for pressing to stop bleeding.

[0031] The inner core fixing device 03 includes an outer pin fixing belt 034 symmetrically fixed on the outer groove 01, an inner pin fixing belt 033 fixed on the transparent inner core 2, and a movable pin 031 for realizing the sliding between the inner pin fixing belt 033 and the outer pin fixing belt 034. To realize the detachable connection between the inner core 2 and the outer groove 01, a magic tape that fits the skin is provided on the inner side of the outer groove 01 away from the hand-held fixing column 011 to facilitate the fixing and stability of the outer groove 01. A hand-held pin handle 032 for restricting the position of the movable pin 031 is provided on the movable pin 031;

[0032] The hand-held pin handle 032 is higher than the inner pin fixing belt 033 and the outer pin fixing belt 034. The movable pin 031 is the same as the hand-held fixing column 011 and is provided with anti-slip patterns.

[0033] The middle of the outer groove 01 is designed with a hollow for placing the inner core 2. The inner core 2 is designed as a pressing piece. When the inner core 2 is not pulled out, it is used to increase the contact surface for pressing the large blood vessel. The outer groove 01 is rectangular, and the long axis direction in the rectangular outer groove 01 is consistent with the blood flow direction of the large blood vessel and is perpendicular to the sliding direction of the movable pin 031. It is convenient to block the blood flow.

[0034] Specific implementation process:

[0035] Situation 1: During an open surgery, an unplanned rupture of a large blood vessel occurs with massive bleeding. At this time, the ruptured and bleeding large blood vessel is closely adhered to the surrounding tissues and cannot be separated. Therefore, it is impossible to use "forceps" or "clip" type instruments to clamp the blood vessel to block the blood flow. At this time, the surgeon takes out the inner core 2 of the detachable medical large blood vessel blunt compression blood flow interrupter (hereinafter referred to as the "interrupter"), adjusts the direction of the interrupter so that the long axis of the interrupter is consistent with the blood flow direction of the large blood vessel, and aligns the center of the interrupter with the bleeding point (see Figure 3 ), then the first assistant grabs any one of the hand-held fixing columns 011 and presses downward forcefully, observes the bleeding condition of the large blood vessel through the transparent interrupter, and presses downward forcefully until the bleeding of the large blood vessel stops. The surgeon holds the hand-held pin handle 032 and moves it towards the center of the interrupter, so that the movable pin 031 disengages from the outer pin fixing belt 034. At this time, the inner core fixing device 03 fails, and the first assistant takes out the inner core 2 from the outer groove 01 (see Figure 2)。The operating surgeon observes the bleeding condition of the major blood vessel through the middle hollow of the outer groove 01, and repairs the rupture of the major blood vessel when the blood flow on both sides of the major blood vessel is blocked. After the repair is completed, the first assistant releases the handheld fixing column 011, so that the outer groove 01 no longer compresses the major blood vessel, the blood flow blockage on both sides of the major blood vessel is released, and it is observed and confirmed that there is no bleeding or blood oozing from the rupture of the major blood vessel. After the operation, the blocker is cleaned and disinfected for the next use.

[0036] This solution aims to design a medical blunt compression blood vessel blocker with a detachable inner core 2, which can timely and effectively block the blood flow of the major blood vessel, and attempts to create a fast, safe and convenient major blood vessel anastomosis environment through the design concept of "pulling out the inner core 2", reduce the damage to surrounding tissues and organs during compression hemostasis, reduce the bleeding time and blood loss, and shorten the operation duration.

[0037] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the technical content disclosed above without departing from the technical solution of the present invention. However, as long as it does not depart from the technical solution content of the present invention, any brief modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
