Screwdrivers are commonly used in orthopaedic surgery to repair a fracture site or rebuildscaffolding around damaged joints & tissue. Up to 6% of traumatic injury patients havefractures; of these patients, ~50% require repair using fixation. Fracture repairs are rising,with market drivers including the aging population (osteoporotic fractures), increasingprevalence of degenerative joint diseases and active lifestyles causing joint wear and tear.There are a number of common problems with existing screwdrivers; they often fail to retainthe screw, & screws can fall into the patient or onto the floor. If the screw falls into the patientit can take time to retrieve; those that fall on to the floor are no longer usable. During theremoval of existing screws there is a risk of stripping & breaking the screw head if thescrewdriver fails to engage properly, making removal problematic and causing the patientdifficulties. A survey of surgeons determined that >60% encountered problems retainingscrews at the end of the screwdriver. Stripped screws & poor screwing technique lengthenoperative time, increase the risk of secondary maximally invasive surgery & the presence ofmetallic shavings residues in cases of screw head destruction.The opportunity exists for Harvard Healthcare Ltd to develop the ‘Tru-Grip LockingScrewdriver’ (TGS), a new orthopaedic screwdriver. The TGS is a hex-tipped driver designedto retain the fastener and prevent screws dropping onto the floor and becoming unusable, orinto the patient, potentially causing tissue damage and costly extension to theatre time.Conservative estimates suggest a minimum of £34K - £62K could be saved by the NHSannually in dropped screws using the TGS, excluding the costs of extra theatre time saved(£15/minute). Cumulative worldwide 5 year sales figures suggest gross profit for HH of over£12.8m, with return on investment expected for Harvard Heathcare in Y1, and for UK Plc inY2.

螺丝刀通常用于骨科手术，以修复骨折部位或在受损关节和组织周围重建支架。高达6%的创伤性损伤患者有骨折;这些患者中，约50%需要使用固定进行修复。随着人口老龄化（骨质疏松性骨折）、退行性关节疾病患病率的增加以及导致关节磨损的活跃生活方式等市场驱动因素的推动，骨折修复正在上升。现有的螺丝刀存在许多常见问题;它们经常无法固定螺钉，螺钉可能会落入患者体内或掉落到地板上。如果螺钉福尔斯落入患者体内，则需要时间取出;掉落在地板上的螺钉将不再可用。在取出现有螺钉的过程中，如果螺丝刀未能正确接合，则存在螺钉头剥离和断裂的风险，从而导致取出问题并给患者带来困难。一项外科医生调查确定，>60%的外科医生在螺丝刀末端固定螺钉时遇到问题。剥脱螺钉和不良的旋入技术延长了手术时间，增加了二次最大侵入性手术的风险，并且在螺钉头破坏的情况下存在金属碎屑残留。哈佛医疗有限公司有机会开发“Tru-Grip锁定螺丝刀”（TGS），一种新的骨科螺丝刀。TGS是一种六角螺丝刀，设计用于固定紧固件，防止螺钉掉落到地板上，无法使用，或进入患者体内，可能导致组织损伤和手术时间延长。保守估计表明，NHS使用TGS每年可节省至少34 K-62 K英镑的螺钉掉落费用，不包括额外手术时间节省的费用（15英镑/分钟）。全球5年累计销售数据表明，HH的毛利润超过1280万英镑，预计哈佛医院将在今年1年获得投资回报，英国公司将在今年2年获得投资回报。
