Description

Comprehensive auxiliary device for cardiac interventional therapy

Technical Field

The invention relates to the field of heart interventional therapy instruments, in particular to a comprehensive auxiliary device for heart interventional therapy.

Background

Atherosclerosis, a condition characterized by lipid-induced thickening of blood vessel walls, can present with angina and/or myocardial infarction (heart attack) or stroke. It poses a major health problem for patients in china and worldwide.

Angioplasty is the widening of a narrowed or blocked blood vessel, particularly an artery caused by atherosclerosis. This technique is now commonly performed by deploying a balloon catheter to the site of the lesion and inflating the balloon in a minimally invasive procedure known as percutaneous intervention ("PCI") while the patient remains awake. Balloon catheters may also be used to deliver stents (with or without a drug release coating) to help maintain the widened lumen of the blood vessel. The cardiac interventionalist visualizes the PCI procedure by fluoroscopy and the use of dyes and/or radiopaque markers on the balloon catheter. Intravenous ultrasound (IVUS) imaging can also be used (or sometimes required) in certain challenging procedures, by which statements have been continued for a large number of patients and health is maintained.

At present, the upper limb or the thigh root is generally adopted for the access operation of the blood vessel. The radial artery is the most commonly used site for arterial puncture. The radial artery of the wrist is located in the longitudinal sulcus between the radial flexor carpus tendon and the lower end of the radius, and the radial artery pulsation can be felt both above and below the radial styloid process. Because the artery position is shallow and relatively fixed, the puncture catheterization is easier. An Allen test is routinely performed before radial artery puncture catheterization to see if adequate collateral shunting from the superficial arch of the ulnar artery after radial artery occlusion. The general procedure used the following steps: the patient usually adopts the supine position, the upper limb is spread on the hand support frame, the puncture person is positioned at the puncture side to place the wrist of the patient on the rolled cloth pad or the sandbag, the palm is upward, and the fist is made hard. The patient arm is stretched out flatly and is abducted, and the palm is up, and the finger points to the person who punctures, places patient's wrist with the little pillow, makes wrist joint lift 5 ~ 8cm to keep wrist joint to be in the hyperextension state. During puncture, the index finger, the middle finger and the ring finger of the left hand of a puncture person are lightly placed at the strongest position of the radial artery pulsation of a patient from far to near from the puncture position to indicate the running direction of the radial artery of the patient, and the position pointed by the index finger is the 'target point' of the puncture.

The main puncturing methods include direct puncturing and penetration, wherein a sheath is inserted after successful puncturing, a channel communicated with a blood vessel is formed under the skin of an upper limb, the sheath is used as a main channel for subsequent guide wire to enter for interventional therapy, and after the therapy is finished, the guide wire is also required to be withdrawn, the sheath is taken out, and the puncturing part is subjected to hemostasis treatment. Based on the operation process, the operation core position of the operation is at the puncture position of the wrist, the interventional device enters and exits through the position, and reaches the target position along the blood vessel. For the above reasons, the intra-operative and post-operative treatment of the wrist puncture site and the puncture artery is the key to ensure smooth operation and reduce postoperative complications.

Example (b): comprehensive auxiliary device for cardiac interventional therapy

The adverse effects of each link in the operation and the postoperative treatment on the operation process and the puncture part are specifically analyzed, and the reasons mainly comprise the following points:

from the operation aspect, the physician usually selects one hand to hold (pinch) the tube above the puncture according to the left and right of the upper limb, and the other hand enters the guide wire along the position out of the sheath tube. The relative control of the guide wire and the sheath tube by two hands realizes the operations of transvascular probing, expanding the channel, placing the stent and the like. This procedure requires the physician to have a very stable hand, which, if shaken, on the one hand, adversely affects the entry path of the guide wire and, on the other hand, the fecal tract can cause dilating damage to the subcutaneous and vascular tracts, with consequent adverse effects on hemostasis and closure. However, doctors keep the wrists in suspension for a long time during operation and need to finely control the guide wires, long-time tension and precise control of muscles are needed, the duration and fineness of force application are difficult to coordinate for small muscle groups on hands, and the fine control is necessarily reduced due to the extension of tension. More serious, the doctor needs to wear the isolation protective clothing weighing thirty kilograms when operating, and the protective clothing at the elbow is also thick and heavy, which increases the burden of the elbow muscle.

In view of the post-operative treatment, the above complications are prevented, for example, bleeding at the puncture site, hematoma, pseudoaneurysm, arteriovenous fistula, arterial thrombosis, etc. The puncture site nursing after interventional therapy usually adopts compression hemostasis, namely, the abdomen of the index finger and the middle finger of the left hand is pressed on the artery puncture point tightly against the cardiac artery, the sheath tube is pulled out of the right hand, the single finger or the double fingers of the left hand are pressed on the puncture point 1cm, meanwhile, the right hand is used for compression with assistance, the puncture site is kept for at least more than 30 minutes, and after no bleeding is confirmed, the bandage is used for further bandaging and compressing for at least 24 hours. However, in practice, there are many important problems in this pressing method, such as how to ensure that the person being pressed can keep a continuous and stable pressing within 30 minutes without dislocation and twisting of the pressing position, which has high requirements for both force and continuous force. For another example, since the front ends of the fingers are not flat, the gaps between adjacent fingers are recessed, which may cause the pressure at the puncture site to change locally, which is not favorable for wound closure. In addition, a larger compression force is needed for the puncture wound of the blood vessel, so that sufficient blood coagulation factors are gathered and hemostasis is realized, similarly, the compression is also needed to be carried out on the wound of the subcutaneous inclined channel caused by the sheath tube correspondingly (inclined), the force at the position is better than the compression force of the blood vessel puncture, the direction is better than the vertical wound extension surface, the existing compression means can not meet the requirements, particularly, the blood vessel wound and the subcutaneous wound can not be considered one by one, and the subcutaneous wound is dislocated after the subcutaneous wound receives the downward compression and certain damage is generated. Problems such as lumps and subcutaneous coagulation may also occur due to excessive pressure applied.

Synthesize above-mentioned problem in the art, the postoperative, design this device can assist in the art and support doctor's wrist, and postoperative subregion oppression hemostasis, and the effect is fine. The specific structure is as follows.

Described as a separately mounted assembly, comprising: bottom mechanism, alignment jig (a pair), oppression mechanism, supporting mechanism.

Bottom mechanism
