Description
本申请要求于2019年8月14日提交中国专利局、申请号为201910750231.7、发明名称为“一种腱鞘炎手术装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on August 14, 2019 with the application number 201910750231.7 and the invention title "A surgical device for tenosynovitis", the entire content of which is incorporated into this application by reference.
本发明涉及医疗器材技术领域,更准确的说涉及一种腱鞘炎手术装置。The invention relates to the technical field of medical equipment, and more precisely to a tenosynovitis surgical device.
腱鞘炎是一种手部肌腱病症,当肌腱无法顺畅通过肌腱时即出现腱鞘炎症状。腱鞘炎大多是由于反复大量的活动肌腱,肌腱和腱鞘间频繁多次摩擦,造成肌腱肿胀,肌腱肿胀处无法顺畅通过腱鞘,导致患者在弯曲或伸直手指时疼痛,严重时肌腱完全无法穿过腱鞘,会导致患者无法弯曲手指。现阶段针对腱鞘炎的治疗手段主要分为保守治疗和手术治疗两种方式。其中保守治疗包括局部制动、理疗、药物、封闭治疗等,保守治疗通常针对腱鞘炎早期的患者,可在一定程度上缓解疼痛,短期效果良好,但是对于病情较为严重的患者作用有限,且容易出现复发。现阶段的手术治疗通常使用外科手术用的普通手术刀片,普通的手术刀片在治疗狭窄性腱鞘炎手术时存在很多缺点,如切口长,损伤大,出血多等,且术后需要缝合手术切口,患者收不损伤较大,且会留下较大的伤痕。针对普通手术刀片存在的缺点,本领域出现了一些专门针对腱鞘炎的手术用具,比如专用的刀片或钩刀等,但是这些手术用具与普通手术刀片的使用方式基本相同,均需在患者手部切开较大的切口,手术过程对医生的操作要求较高,且有些时候医生无法直接观察腱鞘情况,操作精度难以保证。现有的手术用具普遍与普通手术刀片的使用方法类似,在切割腱鞘的过程中容易造成对切口周围神经的损伤,影响患者手部动作,进而影响患者的正常生活。综上,本领域需要一种腱鞘炎手术装置,使用所述腱鞘炎手术装置能够在切口尽可能小的同时,尽可能降低对手部神经的损伤,在治疗成功率高的同时有利于患者术后快速康复。Tenosynovitis is a tendon condition in the hand. Tenosynovitis symptoms occur when the tendon cannot pass through the tendon smoothly. Tenosynovitis is mostly caused by repeated and large amounts of movement of the tendon. Frequent friction between the tendon and the tendon sheath results in swelling of the tendon. The swelling part of the tendon cannot pass through the tendon sheath smoothly, causing pain when the patient is bending or straightening the finger. In severe cases, the tendon cannot pass through the tendon sheath at all. , Will cause the patient to be unable to bend their fingers. At this stage, the treatment methods for tenosynovitis are mainly divided into conservative treatment and surgical treatment. Conservative treatment includes local immobilization, physical therapy, drugs, and occlusive treatment. Conservative treatment is usually aimed at patients with early tenosynovitis. It can relieve pain to a certain extent and has good short-term effects. However, it has limited effect on patients with more serious conditions and is prone relapse. The current surgical treatment usually uses ordinary scalpel blades for surgical operations. Ordinary scalpel blades have many shortcomings in the treatment of stenosing tenosynovitis, such as long incisions, large injuries, heavy bleeding, etc., and the surgical incision needs to be sutured after the operation. It will not be damaged, and will leave large scars. In view of the shortcomings of ordinary surgical blades, some surgical tools specifically for tenosynovitis have appeared in the field, such as special blades or hook knives. However, these surgical tools are basically used in the same way as ordinary surgical blades. To make a larger incision, the operation process of the operation requires a doctor, and sometimes the doctor cannot directly observe the tendon sheath, and the operation accuracy is difficult to guarantee. Existing surgical tools are generally similar to ordinary surgical blades. In the process of cutting the tendon sheath, it is easy to cause damage to the nerves around the incision, affect the patient's hand movement, and then affect the patient's normal life. To sum up, there is a need in the art for a tenosynovitis surgical device. The tenosynovitis surgical device can minimize damage to the hand nerves while reducing the incision as much as possible. The success rate of treatment is high, and the patient can recover quickly after surgery. .
